Experimental investigations of nuclear structure provide a probe to study the strong nuclear force, many properties of which still remain unknown. One powerful way to experimentally investigate nuclear structure is through the mass of the atomic nucleus, as it reveals the binding energy of the nucleus.

Since Bohr set out his interpretation of Quantum Mechanics which
separated small quantum systems from classical measuring systems, the question
as to whether or not there was a physical division between the quantum and the
classical. Is there some criterion which divides the world into quantum bits
and classical bits? Experiments are not answering the question. In particular
I will argue that the 40Kg mirrors of Ligo have already been shown to be
quantum by showing that that the quantum noise of Ligo arises from an

MRI-based assessments of the human brain are critical for research, diagnosis and treatment of neurological disorders. Future clinical practice will demand accurate and consistent quantitative methodology alongside today’s qualitative image evaluations. Consequently, MRI research focuses on developing physical understanding of prevalent techniques and establishing new methods for efficient quantitative analysis. The brain’s complex structure complicates this goal.

My research aims to advance the development pipeline of protein and peptide therapeutics from a biophysical perspective, and covers a spectrum of contributions from methodologies to applications. For methodology contributions, I have developed an unbiased molecular dynamics (MD) simulation tool, Reservoir REMD, and integrated it into GROMACS. It has been benchmarked and shown to give the same results for different initial conformations, even when starting the simulation from a kinetically trapped initial state.

Motivated by the success of the momentum average (MA) approximation for the single-polaron and bipolaron cases, in this thesis we pursue the first generalization of this technique to the case of weakly-doped insulators beyond the Migdal limit. In search of a suitable starting point, we investigate the ground states of a variety of model Hamiltonians, inspired by real materials such as the rare-earth nickelates, polyacetylene, barium bismuthates, and buckminsterfullerene.

Abstract:
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a radio telescope that we built to map the large-scale structure of the Universe between redshifts $0.8<z<2.5$, when dark energy is expected to begin the transition from a decelerating to an accelerating phase in its expansion. It was designed to perform an intensity mapping survey using the 21 cm line of neutral hydrogen, a novel method that has the potential to enable enormous surveys of the distant Universe, but also significant observational challenges to overcome.

Abstract: Since the 1960's a general understanding of the creation of the chemical elements in the universe has existed. However, in recent decades this understanding has undergone refinement in describing the exact astrophysical mechanisms which result in the synthesis of isotopes, particularly those heavier (i.e. more protons) than iron.

Hybrid PET/MRI scanners are becoming more common in research and clinical settings, in particular for their ability to simultaneously acquire unique functional and structural information to probe the healthy and diseased brain. Data from both modalities need to be thoroughly processed to enhance signal-to-noise ratios (SNR), and the development and optimization of analysis algorithms is required to extract meaningful physiological quantities for medical research applications.

Abstract: The bond-dependent Ising interaction present in the Kitaev model has recently attracted considerable attention. The attention has mostly focused on the two-dimensional honeycomb lattice version of the Kitaev model where several materials has been identified as potential realizations. However, one can also imagine realizing simpler one-dimensional Kitaev spin chains that still has a surprisingly rich structure.

Liver cancer is the sixth most common cancer worldwide and radiation therapy has been a non-surgical alternative for treating patients with advanced liver cancer. Dynamic tumor tracking (DTT) has been developed to treat intra-fractionally moving liver tumors with radiation therapy. However, one of the most challenging aspects of DTT is detecting the internal tumor position, which usually relies on implanted markers as a surrogate for tumor position.

Abstract: Quantum materials are hoped to change technology in various aspects. However, most of the desired applications are hindered by the lack of suitable materials. In my group we are using concepts from chemistry to understand, predict and synthesize new quantum materials. In this talk, I will show how simple concepts, such as measuring bond distances, allow us to make predictions about electronic structures of materials, which we can then use to find new quantum materials.

Abstract:
The detection of the 21 cm signal from the Epoch of Reionisation (EoR) is challenging due to the strong astrophysical foregrounds, radio frequency interference (RFI), and ionospheric and instrumental effects. Most if not all observations of the 21 cm signal at high redshifts show so-called “excess variance” in their power spectrum, well beyond what would be expected based on the thermal noise limit. Understanding the sources of the excess is crucial for improving upper limits on the EoR signal.

Abstract:
Computing has revolutionized how modern science is done. Modern scientists use computational techniques to reduce mountains of data, to simulate impossible experiments, and to develop intuition about the behavior of complex systems. Much of the research completed by modern scientists would be impossible without the use of computing. And yet, while computing is a crucial tool of practicing scientists, most modern science curricula do not reflect its importance and utility.

Abstract: Fracton order describes the peculiar phenomena that point excitations in certain strongly interacting systems either cannot move at all or can only move in a lower dimensional sub-manifold. It has recently been discovered in various lattice models, tensor gauge theories, etc. In this talk, we discuss how another powerful field theory framework -- the 2+1D Chern-Simons (CS) gauge theory -- can be used to provide new insight and explore new possibilities in 3+1D fracton order.

Over the past two decades, our knowledge of the Solar System's transneptunian region (often called the Kuiper Belt) has been gradually increasing. Observational surveys have greatly expand the inventory of TNOs, which are distant icy bodies thought to be relics from the giant planet formation and migration era. As more intricate details are unveiled in the TNO orbital and physical properties, several aspects are thought to be tightly linked to the Solar System's early formation.

Abstract:
The majority of baryons in the universe exist outside galaxies, in the circumgalactic (CGM) and intergalactic medium (IGM). The properties of these structures are important to understand as the material they hold is required to fuel ongoing star formation in galaxies. The process of how the gas in the CGM gets into galaxies (and is blown back out through galactic feedback) is still debated, though – in fact, the total mass of the CGM of galaxies is still unknown. This mystery remains due to the near invisibility of the CGM and IGM.

Abstract:
The universe’s biggest galaxies have both vast atmospheres and supermassive central black holes. Coupling between those two components of a large galaxy couple regulates the galaxy’s star formation rate. Models of interactions between a supermassive black hole and the large-scale atmosphere suggest that the energy released as cold gas clouds accrete onto the black hole suspends the atmosphere in a state that is marginally stable to formation of cold clouds.

Abstract: In this talk, I will present a new type of scanning probe microscope, the Quantum Twisting Microscope (QTM), capable of performing local quantum interference measurements at a twistable interface between two quantum materials. Its working principle is based on a unique tip made of an atomically-thin two-dimensional material. This tip allows electrons to coherently tunnel into a sample at many locations at once, with quantum interference between these tunneling events, making it a scanning electronic interferometer.
