Abstract:
We employ quantum simulation of interesting electronic materials using ultracold 6 Li atoms, a composite fermion, as stand-ins for the electrons Quantum simulation of this kind takes advantage of the capability to adhere to a theoretical model, while the tunability of model parameters enables quantitative comparison with theory.

| Event Location: HENN 318 | Speaker: Dr. Katarina Chatziioannou (Caltech)
Abstract:
Detections of neutron stars in binaries through gravitational waves offer a novel way to probe the properties of extremely dense matter. In this talk I will describe the properties of the signals we have observed, what they have already taught us, and what we expect to learn in the future. I will also discuss how information from gravitational waves can be combined and compared against other astrophysical and terrestrial probes of neutron star matter to unveil to the properties of the most dense material objects that we know of.

When a continuous symmetry is spontaneously broken, collective modes emerge. Usually, their spectrum is dominated by the low-energy physics of massless Goldstone modes. Superconductors, that break U(1) symmetry, are different. Here, the Goldstone boson is gapped out due to the Anderson-Higgs mechanism. The superconducting condensate can therefore host a zoo of massive collective excitations that are stable for lack of a gapless decay channel.

| Event Location: HENN 201 | Speaker: Dr. Lia Medeiros, Princeton
Abstract:
New horizon-scale images of the Galactic Center black hole Sagittarius A* (Sgr A*) recently published by the Event Horizon Telescope (EHT) allow for new strong-field tests of the Kerr metric in a previously unexplored regime. I will discuss the recent EHT observations of Sgr A* with a particular focus on how these new results can be used to test fundamental physics. I will briefly touch upon the earlier M87 results as well.

Abstract:
We will discuss experimental results studying the wave-vortex interaction arising from rotating fluid
and superfluid flows. The dynamical equation describing the wave-vortex interaction can be mapped to
scalar fields propagating on an effective rotating black hole. This opens the possibility of studying a
variety of rotating black hole processes in hydrodynamic systems. I will summarise our experimental
efforts resulting in the detection of geodesic motion, quasi-normal modes and superradiance in normal

Myelin, the lipid-rich sheath which wraps around axons, has complex and unique physical and chemical properties which can be used to produce magnetic resonance imaging (MRI) contrast. Developing MRI to quantitatively measure myelin is vital for monitoring the brain and spinal cord in health and disease. This thesis explores four MRI techniques sensitive to myelin; myelin water imaging (MWI), magnetisation transfer (MT), inhomogeneous magnetisation transfer (ihMT) and diffusion imaging.

Abstract:
This presentation is based on materials collected within my research and community-based projects at the First Nations University of Canada and targets three groups of audience: learners, educators and researchers. The materials have been created in three formats: publications, Power Point Presentations and Videos. My intention is to address the importance, doability and advantage of the holistic way of teaching the Science and Mathematics in an example of the integration of modern Science and Indigenous Knowledge elements.

Abstract:
ESA's Gaia mission has provided distances to around 1.5 billion stars and revolutionized stellar astrophysics. Gaia has finally revealed the population
of faint white dwarf stars in the solar neighborhood. We use this dataset to answer fundamental questions about the nature of white dwarfs, including their
mass distribution, cooling physics (crystallization), and ultracool white dwarfs. I will highlight the current challenges in the physics of white dwarf stars and
our efforts to solve them.

Protein aggregation-related diseases, in particular neurodegenerative diseases, are characterized by the aberrant perturbation of the underlying protein conformational ensemble. Effectively presenting epitopes using vaccines, to raise conformationally selective antibodies, is a central problem in treating neurodegenerative diseases.

Abstract:
There is a new class of technologies emerging for observing unmodified proteins in action and at the single molecule level. This colloquium will give an introduction to our nanoaperture optical tweezer approach and overview the developments from other groups also working in the area. I will also review our work on using these nanoapertures to isolate single Erbium emitters in nanocrystals for single photon sources at fiber optic communication wavelengths, and to study resonant energy transfer between two perovskite quantum dots.

Atomic nuclei exhibit many phenomena not limited to excited states, decays, reactions, and clustering. Nuclear processes control the evolution of stars and explain the abundances of chemical elements in the universe. Nuclear physics can be used to answer fundamental questions about underlying particle physics and cosmology, such as the symmetry between matter and antimatter or the nature of neutrinos.

| Event Location: HENN 318 | Speaker: Lars Künkel (PHAS)
Abstract:
Pulsars are rotating neutron stars which emit faint beams of electromagnetic radiation. In pulsar searches large effort is expended to discover these pulses in time- and frequency-resolved data from radio telescopes. Simultaneously recovering the frequency-dependent delay (dispersion) and the periodicity of the signal is a complex and demanding task, which is further exacerbated by the presence of various types of radio-frequency interference (RFI) and observing-system effects.

| Event Location: HENN 318 | Speaker: Dr. Colby Delisle, University of British Columbia
Abstract:
In this talk, I will discuss how matter systems can lose quantum coherence by interacting with an environment consisting of low-energy photons or gravitons. This process will be illustrated using a simple model of an interferometry experiment. I'll focus particularly on how earlier results - which identified a relationship between "soft" photons/gravitons and boundary terms in the electromagnetic and gravitational matter currents - allows one to easily quantify precisely how much decoherence is caused by "leading" and "sub-leading" soft radiation.
