Fission within the Time Dependent Superfluid Local Density Approximation
This thesis investigates fission within the framework of the time dependent superfluid local density approximation (TDSLDA), the most complete microscopic theory to describe low energy nuclear phenomena currently available. ... 
Trapping and cooling twodimensional crystals of barium ions
The design and characterization of a trap specifically designed to create 2D crystals of trappedbarium ions is presented. The trap is used to study the Doppler cooling of 2D crystals. Ions in RF traps are subject to ... 
Interactiondriven dynamical delocalization in a kicked onedimensional ultracold gas
This dissertation reports on the experimental observation of interactiondriven dynamical delocalization in a kicked onedimensional ultracold gas. In the absence of interactions, particles in a onedimensional disordered ... 
Precession frequency analysis for Run2 and Run3 of the Muon g2 experiment
The Fermilab Muon $g2$ experiment aims to measure the anomalous magnetic momentum of the muon, $a_{\mu}$, to 140 part per billion precision. This measurement is compared to the Standard Model (SM) value for $a_{\mu}$ as ... 
Mathematical methods for magnetoencephalography forward and inverse modeling with enhanced spatial resolutions
Nextgeneration magnetoencephalography (MEG) sensors, opticallypumped magnetometers (OPMs), can be placed closer to the head and are expected to measure signals with improved spatial resolutions. This introduces many ... 
Entanglement between Quarks in Hadrons
Entanglement between valence quarks and the sea in hadrons is shown to be deeply connectedto important features of QCD, namely chiral symmetry breaking and confinement. The sea degrees of freedom can be traced over to give ... 
Modeling Hydra from neuron to muscle to behavior
The fundamental question in neuroscience is to understand how single neurons combine to function as a network, and how their activity drives muscles to produce variety of behaviors to interact with the environment and ... 
The Axion Universe
The standard models of cosmology and particle physics have met enormous success. However,there are still a few big questions that remain to be answered. One of these outstanding questions is “what is the dark matter?”. One ... 
Probing electronic correlation and topology in twisted multilayer graphene
MoirÃ© quantum materials, stacked 2D atomic layers with a small twist angle or a slight lattice mismatch, have become emerging platforms to study the physics of correlation, topology, and the interplay between the two. A ... 
Recent Progress in Quantum Gravity: KarchRandall Braneworld, Entanglement Islands and Graviton Mass
In this thesis, we review important recent progress in our understanding of entanglement islands and quantum gravity. We illustrate the concept of entanglement island and its implications to the black hole information ... 
Datadriven modeling and control of quantum dynamics
Control is the factor that delineates quantum science from quantum engineering. Modelbased optimal control is a modern approach to practical control engineering. It designs control laws using optimization based on dynamical ... 
Tuning Superconductivity and Competing Phases in an Ironbased Superconductor with Uniaxial Stress
Unconventional superconductors exhibit strong electronic correlations, quantum criticality, and numerous brokensymmetry collectively ordered phases involving a complex combination of charge, spin, and lattice degrees of ... 
Search for Events with Two Displaced Vertices from PairProduced Neutral LongLived Particles Decaying to Hadronic Jets in the Muon Spectrometer of the ATLAS Detector with Full Run 2 Data
This analysis is a search for events with two displaced vertices reconstructed from the decay of pairproduced neutral, weaklyinteracting, longlived particles using the muon spectrometer of the ATLAS detector. The search ... 
An exploration of datadriven system identification and machine learning for plasma physics
Plasma is the most common state of visible matter in the universe and provides a myriad of scientific and engineering applications. However, the complexity of these systems poses a significant challenge for understanding ... 
FASER tracker performance and electron energy resolution in the FASERv pilot detector
In collider experiments, very light particles are produced in the farforward direction with small angle relative to the beam axis and can travel a long distance before decaying. The ForwArd Search ExpeRiment (FASER) is ... 
Pions in Neutronrich Matter: Implications for Neutron Stars and Supernovae
The effects of pions on astrophysical phenomena have been studied for decades. In the 1970s, Migdal and Sawyer independently proposed that pions could condense in dense matter due to attractive pwave interactions with ... 
A Search for Wavelike Dark Matter with Dielectricallyloaded Multimode Cavities
Dark matter makes up 85% of the matter in the universe and 27% of its energy density, but we don’t know what comprises dark matter. There are several compelling candidates for dark matter that have wavelike properties, ... 
Modeling Complex Multicomponent Materials with FirstPrinciples Based Statistical Mechanics and Machine Learning
Recent progress in the engineering of multicomponent, solidstate compounds for optoelectronic applications has entailed an ever expanding range of material chemistries and a rapid increase in material complexity. For ...
