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.

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.

Abstract: The notion of twisting and stacking two-dimensional van der Waals materials has emerged as a paragon for realizing novel electronic states. With the goal of engineering topological superconductivity, we go beyond the archetypal example of twisted bilayer graphene and consider structures composed of proximitized quantum wires and high-Tc cuprate superconductors.

The Standard Model of particle physics is a powerful theory of nature, yet it does not account for all physical observations. Notably, the nonzero masses of the three neutrino flavours and their transformations into one another suggest the need for an extension of the Standard Model. One such extension postulates the existence of Heavy Neutral Leptons (HNLs, N ) — right-handed neutrino states that do not interact with other particles except through mixing with Standard Model neutrinos. HNLs may generate light neutrino masses through the so-called “seesaw mechanism.”

We study the effects of the Peierls electron-phonon coupling in different multi-band systems. In contrast to the more commonly employed Holstein coupling, which is used in single-band models and is momentumindependent, the momentum-dependent Peierls coupling can explicitly treat coupling to multiple bands. Our results demonstrate the importance of using the Peierls coupling in modelling complex systems

The electromagnetic and gravitational fields transfer information between physical systems. This work is an attempt to better understand how matter systems communicate quantum information with one another using these fields, and also how quantum information about matter is broadcast into the fields themselves. We study the former process in Part I and the latter in Part II, by answering two distinct but related questions.

Electrical conduction becomes non-local when an inhomogeneous electronic distribution is induced with spatial variation shorter than the mean free path (MFP) between momentum-relaxing electronic scattering processes. Two important methods of inducing such a distribution are via the size and skin effects. In the size effect, one or more dimensions of a medium are reduced below the MFP.

The Standard Model (SM) is the governing theory of particle physics. Although its predictions are in excellent agreement with experimental observations, it does not provide a full picture of the physical universe. The Higgs boson is the SM's most recently-discovered particle and a crucial ingredient of the theory. Measuring any deviation between its observed and expected properties could pave the way toward a more complete theory.

Black holes are regions of spacetime from which nothing can escape. This is already strange, but more puzzling is the fact that, over time, quantum mechanics causes black holes to leak energy and disappear. What happens to the objects that fell inside? The unitarity of quantum mechanics suggests one answer, and computations in semiclassical gravity another. To determine which is correct, we need to understand how quantum and gravitational effects interact.

Quantum materials manifest exciting macroscopic electronic properties that emerge from microscopic electron interactions -- such as those between the electron and the lattice. Extensive research effort has been dedicated to understanding the physics of these materials; among these, angle-resolved photoemission spectroscopy (ARPES) has the unique capability of taking ``photos" of the electronic band structure.

The Standard Model of Particle Physics is the prevailing theory for describing the interactions of all observed fundamental particles and three of the four known fundamental interactions. However, despite its profound success, the Standard Model fails to explain some observations, such as dark matter and matter-antimatter asymmetry. Additionally, incorporating Einstein’s theory of general relativity has proven difficult.

Abstract: Quantum computers promise to efficiently solve not only
problems believed to be intractable for classical computers, but also
problems for which verifying the solution is also considered
intractable. This raises the question of how one can check whether
quantum computers are indeed producing correct results. This task,
known as quantum verification, has been highlighted as a significant
challenge on the road to scalable quantum computing technology. We
review the existing approaches and compare them in terms of structure,

Atomistic modeling of phonon-mediated heat transport in single-walled carbon nanotubes (CNTs) dates to the year 2000, when Berber, Kwon and Tománek, by means of molecular dynamics (MD) simulations, predicted a thermal conductivity of up to 6600 W/mK, suggesting extremely efficient heat transfer in these one-dimensional carbon materials.

In the mid-90s I found myself, as a member of the Sudbury Neutrino Observatory (SNO) collaboration, a recipient and custodian of 1000 tonnes of “spare” heavy water, book value $300M. How such a rare asset came to exist in Canada is a complex story of nuclear physics, geopolitics, world war, flight and exile. For a while the tale runs along the fringe of the Manhattan Project saga, but it largely concerns reactors rather than bombs. The story crosses continents (Norway-France-Canada) in circumstances anyone familiar with the news at this moment can readily imagine.

The Canadian Hydrogen Intensity Mapping Experiment (CHIME) has discovered thousands of fast radio bursts (FRBs). The extremely high all-sky rate of FRBs implies that they have the potential to become powerful cosmological probes. Unlocking this potential requires localizing a large sample of FRBs to their host galaxies. Until now, precise localization within the host galaxy has only been accomplished in follow-up observations of repeating sources. Here, we demonstrate the localization of FRB 20210603A using very long baseline interferometry (VLBI) at its time of first detection.
