The dark universe: the interplay of cosmological moduli, axions, and the MSSM
(2023-05)
In this work, we introduce two effective field theories which parameterize a light modulus field interacting both with the MSSM ($\phi$MSSM) and with the MSSM combined with an additional supersymmetric DFSZ axion ($\phi$PQMSSM). ...
Intervalley Scattering in III-V Heterostructures and its Application to Valley Photovoltaic Hot Carrier Solar Cells
(2022-12-16)
The efficiency limit of 33% for a single gap solar cell is not fundamental. Mitigation of thermalization losses which occur when high energy ‘hot’ carriers are only extracted at the same energy as low energy carriers is a ...
Space Application of Novel Solar Cells
(2023-05-12)
Multiple solar cell technologies from three different generations of photovoltaic cells were studied for space applications. The GaAsSb, crystalline first-generation solar cells were studied under low-intensity-low-temperature ...
Interaction Effects in Quantum Wires and One-Dimensional Incoherent Semimetals
(2022-08-04)
In this thesis, we address the effect of interactions in low dimensional
systems. In the first part, using bosonization, we study a microscopic
model of parallel quantum wires constructed from two dimensional Dirac
fermions ...
Generation and Control of Atomic Resonant Squeezed Light
(2022-05)
Quantum metrology is a new emerging technology studying of extreme sensitive and high resolution measurement based on quantum mechanical principles such as quantum entanglement and squeezing, which can potentially revolutionize ...
Enhanced Measurement of Transmission with Quantum States of Light
(2022)
Quantum metrology is the application of quantum mechanics towards the enhancement of
measurements. This is typically achieved through either quantum measurements, such as
photon counting, or using quantum states. In this ...
Nonlinear Processes in Hot Sodium Vapors and Sodium Spinor Bose-Einstein Condensates for Entanglement Generation
(2021-08-05)
The primary purpose of this thesis is to study the generation of quantum entanglement via nonlinear processes in hot sodium vapors and ultracold sodium spinor Bose-Einstein condensates. The creation of entanglement can ...
THERMOPHOTOVOLTAIC DEVICES AND INFRARED PHOTODETECTORS BASED ON INTERBAND CASCADE STRUCTURES
(2020-05-08)
Mid-infrared (IR) optoelectronic devices form the basis for many practical applications such as thermophotovoltaic (TPV) energy conversion, gas sensing, thermal imaging, medical diagnostics, free-space communications, ...
Fluctuation-induced frictional effects on atoms and nanoparticles
(2023-08)
Fluctuations can cause extraordinary effects on atoms and nanoparticles. For example, a neutral but polarizable particle sitting close to a planar surface feels an attraction force towards the surface. This is the well-known ...
Searches For Heavy Resonances In The $R \rightarrow WW \rightarrow \ell\nu\ell\nu$ Decay Channel Using $pp$ Collisions At $\sqrt{s}$ = 13 TeV With The ATLAS Detector At The LHC
(2020-08)
This thesis presents a search for a heavy Higgs-like resonance decaying in the $R \rightarrow WW^{*} \rightarrow \ell\nu\ell\nu$ channel using the ATLAS detector at the Large Hadron Collider. The search uses proton-proton ...
