A test of the gravitational inversesquare law at short distance
(20131114)Proposed theories that unify gravity and quantum mechanics often require Newton's gravitational inversesquare law to fail below some length scale. Additionally, some theorists have proposed the discovery of Dark Energy ... 
The role of nuclear physics in supernovae and the evolution of neutron stars, Neutrino Opacities, Equation of State, Transport Coefficients, and Dark Matter Production
A massive star, of at least eight solar masses, end their life cycle in a sudden, catastrophic collapse under its own gravity. In a thousandth of a second, it can shrink from thousands of kilometers across to a ball of ... 
Theoretical and Numerical Studies of Dynamics in Nucleic Acids based on Experimental NMR Data
(20120913)The collection of work presented in this thesis is directed towards building an understanding of the dynamics of nucleic acid molecules and their components using data obtained from solid state and solution NMR experiments. ... 
Thermodynamics of helium and hydrogen films adsorbed on singlewalled carbon nanotube bundles
(2004)Adsorption of Helium and Hydrogen on bundles of single walled carbon nanotubes (SWCNs) has been studied via heat capacity and volumetric isotherm measurements. These measurements allow conclusions regarding the growth of ... 
Topics in field theory and particle phenomenology
In this thesis, I focus on a few different applications of modern quantum field theory. I start with a model beyond the standard model: Little Flavor Theory and its related collider phenomenology. This model combines a ...

Torsion Pendulum Searches for Macroscopic SpinInteractions as a Window on New Physics
The interactions of intrinsic particle spin offer a powerful window into important aspects of new physics, such as hidden high energy symmetries and CPviolation. This dissertation describes a new spin 20pole torsion ... 
Toward a measurement of atomic parity nonconservation using a single, trapped barium ion
(1999)A single, trapped barium ion presents an excellent opportunity to make a precise atomic parity nonconservation measurement. The relatively perturbationfree singleion trapping environment and high efficiency shelving ... 
Towards SelfCorrecting Quantum Memories
This thesis presents a model of selfcorrecting quantum memories where quantum states are encoded using topological stabilizer codes and error correction is done using local measurements and local dynamics. Quantum noise ... 
Transport properties of chiral pwave superconductornormal metal nanostructures
In this thesis, we present a theory of electron transport for unconventional superconductors. We focus on the superconducting properties of Sr<sub>2</sub>RuO<sub>4</sub>, which is a strong candidate for two dimensional ...

Understanding near Fermilevel electronic structure through xray emission spectroscopy
Atomic and molecular chemical properties are largely determined by the electronic structure of near Fermilevel states. Determining this structure is therefore one of the central tasks in materials characterization and ... 
Use Deuterium Solid State NMR Simulations to Study Dynamics of Peptides Adsorbed onto Inorganic Surfaces
(20130417)This work is directed towards building an understanding of the dynamics of protein/peptide adsorbed on inorganic surfaces. Deuterium solid state NMR(SSNMR) is a very special tool for probing molecule dynamics in solid ... 
Variability of Point Sources of Gamma Rays Detected by the Fermi LargeArea Telescope
The Large Area Telescope (LAT) aboard the Fermi GammaRay Space Telescope has revolutionized gammaray astronomy, allowing the detection of thousands of point sources of gamma rays. Variability studies are of significant ... 
Xray spectroscopy studies of nonradiative energy transfer processes in luminescent lanthanide materials
Luminescent materials play important roles in energy sciences, through solid state lighting and possible applications in solar energy utilization, and in biomedical research and applications, such as in immunoassays and ...
