Toward Maps of Exoplanet Surfaces
Event Information:
Perhaps the simplest question that one can ask of a distant star or planet is, "What does it actually look like?" Even the best interferometers can only give us limited information about the surfaces of select giant and/or nearby stars, while the direct imaging of exoplanet surfaces is all but impossible. Fortunately, several techniques exist that allow us to indirectly infer what the surfaces of stars and exoplanets look like from precise photometric light curves and high resolution spectral timeseries. In this talk, I will review previous approaches to mapping the surfaces of stars as well as recent results in the nascent field of exocartography. I will discuss the mathematical theory behind the mapping problem, including its degeneracies and limitations, and present several novel approaches to producing surface maps of stars and exoplanets. Finally, I will show how these maps can be used to learn about the physics of stellar surfaces, the dynamics of gas giant atmospheres, and surface processes on solar system objects. I will end with a look to the future, showing how these techniques can pave the way to the characterization of terrestrial exoplanets in the habitable zones of their stars with upcoming instrumentation.

Electronic Processes in Carbon-Based Nanostructured Materials and Devices
Event Information:
Graphene and solution-processed organic (plastic) semiconductors combine unique electronic, photoelectronic and mechanical properties that opens an emerging field of exciting research at the interface between two conceptually different, but complementary types of nanostructured electronic materials. These novel heterobilayer hybrid nanocomposites bear great potential for self-powered buildings, remote electronic gadgets, health sensors and medical implants due to their unique electronic properties, in combination with low-cost processing, biocompatibility and inherent mechanical flexibility.
This talk will discuss our results on the development and understanding of novel carbon-based electronics and photovoltaics by applying a multidisciplinary approach at the interplay of cutting edge materials science, interface and device physics. The first part will be devoted to our achievements in the area of device physics through the fabrication and advanced characterization of organic bulk-heterojunction solar cells. Then, I will present our recent studies on temperature and light modulated doping effects and charge transport in graphene/ conjugated polyelectrolyte (CPE) or hybrid organic-inorganic perovksite heterobilayer nanocomposites. At the end of this talk I will explain the working principle of low-cost pencil-drawn energy harvesters on flexible substrates, called ionic-organic electronic ratchets.

CM Seminar : Dimensional reduction by geometrical frustration
Event Information:
Dimensionality is one of the most important factors that critically govern phase transitions and elementary excitations in solids. Low dimensional spin systems are approximately materialized in actual three-dimensional (3D) crystals via anisotropic chemical bonding. However, dimensionality may not be always a “built-in” character of a crystal structure but can be an emergent property in a frustrated spin system. One example is found in BaCu2Si2O6, in which BEC of triplons takes an essentially 2D character near a quantum critical point between the gapped state and long-range order [1]. This is ascribed to a geometrical frustration between neighboring square lattices that stack in a staggered manner so as to cancel the inter-layer couplings. Thus, true two-dimensionality seems to be preserved by frustration in the 3D lattice.
Here we report “dimensional reduction” by geometrical frustration in three spin systems. In Ca3ReO5Cl2 comprising an anisotropic triangular lattice (ATL) made of spin-1/2 Re6+ ions, one dimensionalization is clearly evidenced by magnetic susceptibility and heat capacity measurements, in spite that the inter-chain zigzag coupling is significantly large: J’/J = 0.42 [2]. A similar one dimensionalization gives a singlet ground state in the two-leg spin ladder compound SrCu2O3 and a 1D spin liquid in the three-leg spin ladder compound Sr2Cu3O5 [3].
Figure 1: Magnetic order in pharmacosiderite
Further interesting dimensional reduction is recently observed in a natural mineral, pharmocosiderite (H3O)Fe4(AsO4)3(OH)4•5.5H2O [4]. It comprises tetrahedral clusters made of spin-5/2 Fe3+ ions in a cubic primitive cell (Fig. 1). The antiferromagnetic Heisenberg interactions are determined as J = 10.6 K and J’ = 2.9 K. A q = 0, Γ5 order sets in at 6 K, in which a 2D spin fluctuation is observed. This is ascribed to a two dimensionalization by frustration only for the J’ tetrahedral coupling along the c axis. It is emphasized that, compared with the ATL antiferromagnets, the resulting 2D anisotropy is not fixed to the crystal lattice but is induced by the evolution of magnetic correlations towards the LRO.

New Probes of Black Hole Variability
Event Information:
I will discuss the power of new observations of variable black holes (supermassive and stellar mass systems) to probe their growth and evolution. I will touch on our Milky Way's black hole Sgr A*, the Virgo cluster's M87, changing-look quasars, the multitude of systems now being discovered by LIGO/Virgo, and briefly explore how we can continue to push this frontier with a next generation of observatories.

Optical photon generation from a superconducting qubit
Event Information:
The ability to store, transfer, and process quantum information promises to transform how we calculate, communicate, and measure. The realization of large-scale quantum systems that can achieve these tasks is an outstanding challenge and an exciting frontier in modern physics. In the past two decades, superconducting circuits based on Josephson junctions emerged as a promising platform for processing quantum information. However, these systems operate at low temperatures and microwave frequencies, and require a coherent interface with optical photons to transfer quantum information across long distances.
In this talk, I will present our recent experiments demonstrating quantum transduction of a superconducting qubit excitation to an optical photon. I will describe how we use mesoscopic mechanical oscillators in their quantum ground states to convert single photons from microwave frequencies to the optical domain. I will conclude by discussing the prospects of this approach for realizing future quantum networks based on superconducting quantum processors and mechanical quantum memories.

Winds of Change around Black Holes
Event Information:
Accretion disks, where matter with angular momentum spirals down through a disk, occur around objects ranging from the youngest stars to supermassive black holes. But not all of this material reaches the center of the disk. Instead, some material is accelerated away from the disk. These outflows can be ejected in a narrow opening angle (what astronomers call "jets") or can be relatively unfocused (what astronomers call "winds"). While we do not know the precise processes that accelerate and collimate winds and jets, magnetic fields almost certainly play a key role. My team and I study black hole X-ray binaries, stellar-mass black holes accreting from a nearby star. We combine observations across the electromagnetic spectrum to learn about the physics of accretion and jets. In this talk, I will discuss how we have revealed two new windows onto the physics of inflows and outflows in X-ray binaries: fast variability measured across the electromagnetic spectrum (which provides the potential to accurately identify the accretion physics that launch relativistic jets) and the modelling of changes in the X-ray brightness of black hole X-ray binaries (which implies that strong winds from the accretion disk are universal). With the advent of new and upcoming facilities, we have a huge potential to take advantage of these winds of change in the next decade.
Speaker: Dr. Gregory Sivakoff is currently an Associate Professor in the University of Alberta Department of Physics, where he has been a faculty member since 2011. He and his group's primary research focuses on multi-wavelength observations of compact objects (white dwarfs, neutron stars, and black holes), tying together a wide range of data to better probe important physics around compact objects. These multi-wavelength observations stretch across nearly the entire electromagnetic spectrum, and are made by facilities across the world and above it. Two classes of objects stand out among the wide range of compact objects he studies: X-ray binaries, neutron stars or black holes that accrete material from a nearby donor star; and the relativistic outflows (jets) from supermassive black holes that are responsible for (at least some) astrophysical neutrinos that have recently been detected. Dr. Sivakoff also has strong interests in Education & Public Outreach; in addition to his multiple pop-culture inspired public talks like, "Black Holes and Revelations" and "Fantastic Black Holes and How to Find Them", he is a strong advocate of citizen science. This support includes sitting on the board of the American Association of Variable Star Observers, an international non-profit organization of variable star observers whose mission is to enable anyone, anywhere, to participate in scientific discovery through variable star astronomy. In 2018 he was selected as the inaugural Telus World of Science Edmonton Science Fellow, which recognizes an outstanding researcher or innovator based in Northern Alberta, and was the recipient of the University of Alberta Faculty of Science Research Award.

Theory error bars for nuclei
Event Information:
In the precision era of low-energy nuclear physics it is no longer acceptable that only experimentalists practice robust uncertainty quantification. Theorists must also generate honest error estimates. Bayesian statistics is well-suited for this task, by quantifying the systematic errors from models with guidance from theoretical expectations about omitted physics. Bayesian methods are being developed and applied to calculate and validate error bands for a wide range of nuclear observables, to determine the limits of the nuclear landscape, to help in the design of experiments, and to catalyze physics discovery. I will give a basic overview of the Bayesian approach to theory errors and survey the recent applications.

Galaxy evolution across cosmic time
Event Information:
Massive galaxies provide a unique laboratory to investigate physical mechanisms driving galaxy evolution. While the initial condition for their formation is provided by their cosmological environment, observations have revealed that galaxies have acquired diverse structures, colours and kinematics already in the first few billion years after the Big Bang. Galaxy evolution is thus driven by a myriad of processes on different scales, such as gravity, heating and cooling, feedback, and phase transition. While our characterization of distant galaxies has improved in recent years with observations using the Hubble Space Telescope and the Atacama Large Millimeter Array, fundamental questions remain. What processes regulate star formation in galaxies? What is the role of supermassive blackholes in shaping their host galaxies? I will discuss how these questions are best tackled with a multi-wavelength approach, enabling a comprehensive census of gas and stars in galaxies. The research area of galaxy evolution is entering a transformative era with the launch of the James Webb Space Telescope in 2021, as it will detect the first galaxies and provide unprecedented details on galaxies at their peak of formation. Canada is well-positioned to make great strides in this field given its access to the most powerful telescopes and the construction of the Gemini Infrared Multi-Object Spectrograph, the first instrument of its kind that provides sharp, 3D views of distant galaxies. I will describe a vision for harnessing these facilities to answer the most pressing questions in galaxy formation and evolution.

Aspects of Correlated World Line (CWL) Theory
Event Information:
We are now approaching a time when experimental groups will try studying quantum behavior of objects with masses of order the Planck mass. Many have argued that it is at this scale that Quantum Mechanics may break down because of gravitational effects, and CWL theory is a concrete theory which makes such a prediction. In a recent seminar Philip Stamp has discussed introductory aspects of the theory before proceeding to discuss possible experiments in detail. In this talk I will further expand on the theory, discussing: its general structure and rules for computation, its similarities and differences with conventional quantum theory, classes of states, and some results for CWL corrections to correlation functions and transition amplitudes.

Clash of the Titans: Galaxy mergers in the nearby Universe
Event Information:
Astronomy's current model of galaxy evolution is built on a foundation of hierarchical growth, in which small galaxies merge together to form larger ones. In addition to the simple accrual of mass, this merging process is predicted to fundamentally change the galaxies’ properties, such as dramatic morphological transformations, the triggering of bursts of star formation and high rates of accretion onto the central supermassive black hole. In this talk I will explain the physical processes behind these predictions, and present the observations that we are performing in order to test the theory. Although many of the predictions are indeed borne out by experiment, there have been some surprising conflicts as well, that demand revisions to our models of how mergers shape galaxy evolution.

"Quantum Transport in 2D Topological Insulators"
Event Information:
Final PhD Oral Examination
Abstract:
Topological insulators (TI) have been the subject of intense theoretical and experimental investigation due to their distinct electronic properties compared to conventional electronic systems. This thesis investigates electronic properties of two topological insulators, InAs/GaSb double quantum wells and monolayer WTe2, through transport measurements at ultra-low temperatures.
Using double gate geometry, InAs/GaSb quantum wells can be tuned between topological and trivial states. Previous works have reported the existence of robust helical edge conduction in the inverted regime. Here, we found an enhanced edge conduction in the trivial state with superficial similarity to the observed edge conduction in those reports. However, using various transport techniques and sample geometries, the edge conduction in our samples was found to have a non-helical origin.
Another topological insulator that is studied in this thesis is monolayer WTe2. Here, we report that monolayer WTe2, already known to be a 2D TI, becomes a superconductor by mild electrostatic doping, at temperatures below 1K. The 2D TI-superconductor transition can be easily driven by applying a small gate voltage. Furthermore, we observed peculiar features such as enhancement of parallel critical magnetic field above the Pauli limit possibly, from spin orbit scattering.

From Magnets to the Nuclear Force
Event Information:
Anomaly matching is one of the few universally applicable tools to constrain the dynamics of strongly coupled quantum systems. I will give an overview of 't Hooft anomalies and their applications. Anomalies arise in a wide range of physical systems, ranging from pedagogical quantum mechanical models to Heisenberg spin chains to quantum chromodynamics. I will then discuss implications of anomalies in gapless phases described by conformal field theory. Using the conformal bootstrap techniques, I will prove rigorous constraints on the spectrum from anomalies.

CM Seminar : Topological Physics in HgTe-based Quantum Devices
Event Information:
Suitably structured HgTe is a topological insulator in both 2- (a quantum well wider than some 6.3 nm) and 3 (an epilayer grown under tensile strain) dimensions. The material has favorable properties for quantum transport studies, i.e. a good mobility and a complete absence of bulk carriers, which allowed us to demonstrate variety of novel transport effects.
A novel development is the use of wet etching technologies to fabricate HgTe based nanostructures. This approach allows a much higher transport quality in nanodevices. We have fabricated quantum point contacts, which show remarkable spin selective transport behavior. Additionally, we have developed a gate-training technique, which pushes the scattering length for the quantum spin Hall effect well above 100 mm. A further recent development is the realization that van Hove singularities in the valence band may give rise to remarkable transport effect, such as e.g. the realization of a n=-1 quantum Hall plateau at fields as low as 20 mT.
Another regime we can study is topological superconductivity, achieved by proximity-inducing superconductivity in the topological surface states. Special emphasis will be given to recent results on the ac Josephson effect. We will present data on Shapiro step behavior that is a very strong indication for the presence of a gapless Andreev mode in our Josephson junctions, both in 2- and in 3-dimensional structure. An additional and very direct evidence for the presence of a zero mode is our observation of Josephson radiation at an energy equal to half the superconducting gap.
Controlling the strain of the HgTe layers strain opens up yet another line a research. We have recently optimized MBE growth of so-called virtual substrates ((Cd,Zn)Te superlattices as a buffer on a GaAs substrate), that allow us to vary the strain from 0.4% tensile to 1.5% compressive. While tensile strain turns 3-dimensional HgTe into a narrow gap insulator, compressive strain turns the material into a topological (Dirac/Weyl) semimetal, exhibiting clear signs of the Adler-Bell-Jackiw anomaly in its magnetoresistance.

CM Seminar : Ultrafast Resonant X-ray Scattering on Quantum Materials at LCLS
Event Information:
Abstract: The use of ultrashort optical and X-ray pulses offers new opportunities to study fundamental interactions in materials exhibiting unconventional quantum states, such as stripes, charge density waves and high-temperature superconductivity. In this talk I will first review recent results produced at the LCLS in this field. I will then focus on ultrafast resonant X-ray scattering experiments on YBa2Cu3O6+x single crystals. Ultrashort infrared pulses produce a non-thermal quench of the superconducting state while X-ray pulses detect the reaction of the charge density waves. At low fluences a transient enhancement of charge density waves is observed, directly revealing the interaction between the two order parameters on their natural timescales.
Biosketch: Giacomo Coslovich has spent his career studying complex materials using ultrafast lasers. He did his graduate research at the University of Trieste, Italy, receiving his PhD in 2011. He then took up a postdoctoral position at Lawrence Berkeley National Laboratory. In 2015, he became a staff scientist at SLAC, where he studies high-temperature superconductors using SLAC’s LCLS X-ray laser.

Observing planet formation in action in protoplanetary disks
Event Information:
Successful exoplanet surveys in the last decade have revealed that planets are ubiquitous throughout the Milky Way, and show a large diversity in mass, location and composition compared to our Solar System. At the same time, new facilities such as the Atacama Large Millimeter/submillimeter Array (ALMA) and optical/infrared facilities such as Gemini/GPI have provided us with sharper images than ever before of protoplanetary disks around young stars, the birth cradles of planets. The physical processes in disks leading to the formation of planets can now be traced directly in images. The high spatial resolution has revealed unexpected structures in disks, such as rings, gaps, asymmetries and spiral arms, and the enormous jump in sensitivity has provided the tools for both large, statistically relevant surveys and deep, sensitive molecular line studies. These observations have revolutionized our view of planet formation, disk formation and disk evolution, bringing model simulations and observations to the same level of detail. At the same time, these results have led to many new questions about the origin of planets and the physical processes in disks. Upcoming observational facilities, such as the Next Generation Very Large Array and Square Kilometre Array in radio, and the Thirty Meter Telescope and James Webb Space Telescope in the infrared, will create new possibilities to explore the planet formation process in the terrestrial regime in the inner few AU of the disk. In this talk, I will discuss the current transformation in our understanding of planet formation and the next steps and challenges in connecting theory with exoplanet demographics and protoplanetary disk observations.

Calibration of the Advanced LIGO detectors
Event Information:
Ground-based gravitational wave detectors are kilometre-scale laser interferometers that operate in a closed servo control loop configuration. The output data stream must be accurately and precisely calibrated to estimate the impinging gravitational wave signal. Gravitational waveforms, astrophysical source parameters, and cosmological parameter estimates all rely upon this calibrated data stream, so it is critical that calibration be done with a high degree of accuracy and precision. In this talk, I will describe how the Advanced LIGO detectors are calibrated and the challenges in accurately and precisely determining the calibration on the scale of 1e-19 m at the 1% level.

Fractionalization and emergent gauge field in condensed matter
Event Information:
The entanglement pattern of a quantum many-body state can be characterized by quasiparticles and emergent gauge fields, much like those found in Maxwell's theory. These low energy degrees of freedom "emerge" from the quantum structure of the strongly correlated system, and appear to be more diverse and exotic than their elementary constitute. In particular, one of the key paradigm shifts in modern condensed matter physics has been the observation of symmetry fractionalization where the quasiparticle degree of freedom exhibit fractional quantum number and statistics. An important question is to understand what types of symmetry fractionalization patterns can appear in nature and how do they interplay with the emergent gauge field.
In this talk, she reviews the basic aspects of symmetry fractionalization and emergent gauge fields in condensed matter systems. In addition, she will introduce a new type of quantum many-body phase, dubbed "fracton phase of matter" where the fractionalized sub-dimensional quasiparticle and emergent higher-rank gauge fields exhibit constrained dynamics as a consequence of subsystem symmetry.

Interstellar asteroids and comets: planetary dynamics meets galactic dynamics
Event Information:
In 2017, the first asteroid to enter our Solar System from interstellar space was discovered at the Pan-STARRS telescope in Hawaii, and has now been named 'Oumuamua, a Hawaiian term which signifies 'Messenger from Afar'. In 2019 a second interstellar visitor, comet Borisov (named after its discoverer) appeared. Curiously, they have contrasting properties: 'Oumuamua is rocky and relatively slow (both unexpected beforehand) while Borisov is the reverse: icy and fast. Much could be learned about this new class of object if we knew their sources and/or the mechanism(s) by which they are produced, both of which are uncertain. I'll outline some of the efforts being made to back-track these puzzling visitors to their points of origin, somewhere within our Milky Way galaxy.

Exploring Quantum Materials with Atomic Qubit Sensor
Event Information:
We are witnessing a revolution in which quantum phenomena are being harnessed for next-generation technology. A central challenge in this effort is to gain detailed insights in the behaviors of electrons and spins in quantum materials. In this context, quantum sensing technology realized with nitrogen vacancy (NV) center in diamond has emerged as a powerful probe of advanced materials and devices. Due to its ability to sense magnetic field with high spatial resolution over wide temperature and dynamic range, NV sensors enable the exploration of condensed matter phenomena in parameter space inaccessible to existing probes. In this talk, he will discuss our application of NV quantum sensing technology to study correlated electronic and spin phenomena. We have directly imaged, for the first time, the viscous Poiseuille flow of the Dirac fluid in neutral graphene, a finding that holds implication for other strongly correlated electrons such as those in high-Tc superconductors. Enabled by the NV platform, we have developed new capabilities for probing coherent spin-waves, which can be applied to study novel magnetic materials and spintronic devices, and a tool for charactering low-dimensional high-Tc cuprates without electrical contacts. Looking forward, he will highlight opportunities for advancing the frontiers of quantum materials and quantum technology enabled by NVs and other solid-state atomic qubits.
