Time-Dependent Quantum Reactive Scattering in Hyperspherical Coordinates
(2013)
We present a time-dependent hyperspherical, wave packet method for calculating three atom state-to-state S-matrix elements.
Quantum Hall ferromagnetism in indium antimonide quantum wells.
(2005)
Antimony-based III-V semiconductors are getting increasing attention for device applications and fundamental research thanks to advances made in their growth and understanding of their properties. InSb with its extremely ...
Quantum Effects in Nodal-line Semimetals
(2020)
Topological materials such as Dirac and Weyl semimetals have relativistic quasiparticles at a discrete number of points in the Brillouin zone. Those materials are semimetalas in the bulk but host metallic surface states ...
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 ...
Co-Spatial UV-Optical HST/STIS Spectra of Seven Galactic Planetary Nebulae: Nebular and Stellar Properties
(2017)
This project had two main goals: (1) to investigate to what extent planetary nebulae (PNe) are chemically homogeneous; and (2) to provide physical constraints on the central star properties of each PN. The first goal was ...
OBSERVATION OF SINGLE TOP QUARK WITH ASSOCIATED Z BOSON PRODUCTION AT THE LARGE HADRON COLLIDER USING THE ATLAS DETECTOR
(2019)
The Standard Model of particle physics is the most well tested theory in modern physics.
It provides the most fundamental description of the natural world using only a handful of particles and their interactions.
At ...
Coherent control and geometric phase
(2008)
We present the ability to coherently control triatomic chemical reactions with pulsed-laser techniques. We show that one can control the final state probability distribution of triatomic chemical reactions with nearly 100% ...
Supersymmetry and the Prisoner of Naturalness
(2017-07-27)
In this work, I will address three concerns of supersymmetry. The first is the notion of naturalness and how much fine-tuning exists in a model. Historical measures, ∆ HS and ∆ BG , have led to an over estimate of the ...
TYPE-II QUANTUM WELL HOT CARRIER SOLAR CELLS
(2018-12-14)
Hot carrier solar cells are a third generation photovoltaic technology, which aims to increase power conversion efficiency of solar cells beyond the fundamental Shockley-Queisser limit (33%). A major source of loss in ...
