Raman Studies of Surface Phonons in the Topological Insulators Bi2Se3 and Bi2Te3
(2018)
Temperature- and wavelength- dependent Raman studies of the topological insulators Bi2Se3 and Bi2Te3 are presented. At low temperatures and in the A symmetry scattering channel, we observe additional weak modes which we ...
Exploring Drug Bioaccumulation and Stabilization with Respect to Endolysosomal Ion Homeostasis Using a Systems-Based Mathematical Modeling Approach
(2018)
Even though most of the FDA approved drugs currently out in the market and in the process of development are weakly basic drugs, the bioaccumulation and stabilization of these drugs are not well understood. For this purpose, ...
Efficient Algorithms for Light Transmission, Focusing and Scattering Matrix Retrieval in Highly Diffusive 3D Random Media
(2018)
Wavefront shaping provides an increasingly appealing avenue for imaging and other applications that require controlling electromagnetic waves passing through complex and disordered media. Indeed, these techniques allow ...
Two-particle Response Functions in Strongly Correlated Electron Systems
(2017)
In this thesis, we use the dynamical cluster approximation to study strongly correlated electron systems, especially from the angle of two-particle quantities, such as dynamical susceptibilities and vertex functions.
The ...
Supersonic, Single-Mode and Dual-Mode Kelvin-Helmholtz Instability Experiments Driven by a Laser-Produced Shockwave
(2017)
We developed a novel experimental platform that utilizes a laser-produced shockwave to study the evolution of hydrodynamic instabilities in a steady, supersonic (compressible) flow, from precision-machined and well-characterized ...
A Measurement of the Permanent Electric Dipole Moment of 129 Xe
(2019)
Searches for permanent electric dipole moments (EDMs) are a powerful way to investigate Beyond-the-Standard-Model CP-violation. This work describes the development of a new technique to measure the EDM of 129Xe with a 3He ...
Fast Magnetic Reconnection in Relativistic Laser-Plasma Interactions.
(2016)
Magnetic reconnection is a fundamental plasma process involving the transfer of magnetic potential energy to plasma kinetic energy through changes in the magnetic field topology. Results are presented of experimental ...
First-Principles Calculations of Auger Recombination in Optoelectronic Materials
(2019)
Lighting currently uses around 15% of global energy expenditure. Reducing this energy usage would be an important part of reducing the effects of global climate change. LEDs (light-emitting diodes) could be a more efficient ...
Five-Dimensional Gauged Supergravity with Higher Derivatives.
(2012)
This thesis summarizes the recent developments on the study of five-dimensional
gauged supergravity with higher derivative terms, emphasizing in particular the ap-
plication to understanding the hydrodynamic properties of ...
Phase-Contrast X-Ray Imaging of Microstructure and Fatigue-Crack Propagation in Single-Crystal Nickel-Base Superalloys.
(2012)
Single-crystal nickel-base superalloys are ubiquitous in demanding turbine-blade applications, and they owe their remarkable resilience to their dendritic, hierarchical microstructure and complex composition. During normal ...
