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.

| Event Location: HENN 318 | Speaker: Dr. Mukremin Kilic, University of Oklahoma
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.

| Event Location: HEBB 114 | Speaker: Dr. Reuven Gordon (UVic)
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.

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.
