Time dependent radiative transfer: Application on core collapse SNe and cosmic recombination
(2010)
I have conducted my PhD dissertation research at the department of Physics and As-
Naturalness in Supersymmetry
(2015-06)
Weak scale supersymmetry solves the Big Hierarchy problem of the Standard Model. But recent severe sparticle mass limits from the LHC accentuate the Little Hierarchy Problem: Why are the W , Z and h masses so small (∼ 100 ...
Experimental Studies of Cesium Rydberg Atom Pair Interactions
(2009)
This thesis describes experimental studies of Rydberg atom pair interactions. A new technique is described that combines trapping of ultracold Cesium atoms with Rydberg tagging time-of-flight spectroscopy to attain a ...
Search for third generation vector-like leptons with the ATLAS detector
(2022-03-09)
The Standard Model of particle physics provides a concise description of the building blocks of our universe in terms of fundamental particles and their interactions. It is an extremely successful theory, providing a ...
Microwave Electrometry with Rydberg Eletromagnetically Induced Transparency in Vapor Cells
(2016-07-20)
An atom-based approach is presented to detect absolute microwave (MW) electric fields (E-fields). The approach uses Rydberg atoms in vapor cells at room temperature. The MW E-field measurements utilize a bright resonance ...
An Ultraviolet Survey of the DA White Dwarf Population of the Galaxy
(2023-08-04)
DA white dwarfs are the most common type of white dwarf in our Galaxy. Hence, it is important to study the DA white dwarf population as thoroughly as possible. In this dissertation, I present our work using the Galaxy ...
Heavenly metal: A study of neutron-capture element abundances in metal-poor galactic halo stars.
(1998)
New abundances for neutron-capture elements in a large sample of metal-poor giants from the Bond survey in addition to 3 well known individual cases, are presented. The spectra for the Bond Giants were acquired with the ...
Collective Behaviors of Quantum Emitters Coupled to a Structured Photonic Environment
(2023-07)
The study of a quantum system coupled to an environment plays an indispensable role in expanding our understanding of quantum mechanics. It has a broad impact, encompassing fundamental inquiries in quantum physics as well ...
Confined Quantum Systems: Beyond Harmonic Order in Dimensional Perturbation Theory
(2008)
We generalize the harmonic-order N-body DPT method for an isotropically confined quantum system of identical interacting bosons to first-anharmonic order and, in principle, higher orders. We introduce a graphical decomposition ...
Many-body dimensional perturbation theory for quantum confined systems with a focus on atomic gas Bose-Einstein condensates.
(2003)
Feshbach resonances notwithstanding, most experimentally realized atomic-vapor condensates are dilute and are best described by the mean-field Gross-Pitaevskii equation. For this reason, we use dimensional scaling methods ...
