Real-Time Dynamics of Electrons and Phonons from First Principles
… model. This dissertation develops and applies a real-time, ab initio framework based on the time-dependent Boltzmann equation (TDBE) to investigate coupled electron–phonon dynamics in crystalline solids from femtosecond to picosecond timescales. The approach explicitly resolves the dynamics of …

New frontiers of expression through real-time dynamics measurement of violin bows
The violin has long been admired as one of the most beautiful, complex, and challenging musical instruments. With its capacity for nuance, richness of tone, and flexibility of range, its expressive qualities have been surpassed by none, despite the fact that its construction has not been changed …

Quantum Transport of Electronic Excitations through Macromolecules
The investigation of real-time dynamics of charged and neutral quantum excitation propagating through macromolecular systems is receiving growing attention due to its potentially countless applications in nano-scale (opto-)electronics and in biophysics. Several key issues have not been fully …

Dynamics of finite momentum Bose polarons
… an interspecies Feshbach resonance. Using the time-dependent variational approach, we study both ground state properties and quench dynamics of the system after a sudden immersion of the impurity into the BEC. We find evidence of a ground state phase transition when the impurity has a velocity …

SPACE CHARGE LIMITED DIELECTRIC BREAKDOWN, OR: HOW I LEARNED TO STOP WORRYING AND LOVE APPROXIMATIONS
… electron deposition within PMMA. To capture the real time dynamics of the breakdown front, high speed direct and streak imaging were employed, and a sharply localized front was observed whose velocity increased with embedded charge density, in agreement with SCLF predictions. To characterize the …

Aspects of Nonperturbative Heavy Quark Physics
… are an interesting corner of Quantum Chromo-Dynamics (QCD) due to the fact that their masses are much heavier than the typical QCD interaction energy ΛQCD. Due to this scale separation, it is possible to describe these heavy quarks by Effective Field Theories (EFTs) that simplify their …

A Signal to Divide: Apoptotic Extracellular Vesicles as Carriers of Mitogenic and Immunogenic Signals
… by assessing proteomic contents and studying real-time dynamics of AEVs. In both systems, I found AEVs to be enriched in molecules that can modulate cell proliferation and immune cell dynamics.</p> <p>In larval zebrafish, epithelial stem cell-specific ablation induces apoptosis, enabling the …

Dihedral non-Abelian Lattice Gauge Theories: Physics and Quantum Simulation
… simulator offers a promising route to regimes---real-time dynamics, finite baryon density---that lie beyond the reach of Euclidean Monte Carlo methods. With the ultimate goal of overcoming these shortcomings, over the last decade, quantum simulations of Abelian lattice gauge theories have …

A Double-Error Correction Computational Model of Learning
… Error model, a general computational model of real-time learning is presented. It builds upon previous real-time error-correction models and assumes that associative connections form not only between stimuli and reinforcers, but between all types of stimuli in a connectionist network. The …
