Single barium ion spectroscopy: light shifts, hyperfine structure, and progress on an optical frequency standard and atomic parity violation
(2007)Single trapped ions are ideal systems in which to test atomic physics at high precision: they are effectively isolated atoms held at rest and largely free from perturbing interactions. This thesis describes several projects ... 
A SQUIDBased RF Cavity Search for Dark Matter Axions
(20130725)The axion is a hypothetical elementary particle resulting from a solution to the “StrongCP” problem. This serious problem in the standard model of particle physics is manifested as a 10<super>10</super> discrepancy ... 
Strange phases in neutron star matter
(2002)Neutron stars are produced in nature as the remnants of corecollapse supernovae. Their masses lie in the range 12 M⊙ and they possess radii of order 10 km, yielding central densities of several times the density of ... 
A Study of Neutrino Oscillation Models with SuperKamiokande Atmospheric Neutrino Data
(20130225)The rapidly evolving field of neutrino oscillations continues to offer exciting experimental results as it enters the era of precision measurements. The mixing angles and masssquared splittings governing neutrino oscillations ... 
Study of Strongly Coupled Systems via Probe Brane Constructions
In this thesis, we present our study towards better understanding of the strongly coupled systems with extra matter content in the fundamental representation of some prescribed global symmetry group in the quenched ... 
A SubMillimeter ParallelPlate Test of Gravity
Newton's inversesquare law of gravitation is the oldest standing mathematical description of a fundamental interaction. Experimental tests of gravity's distancedependence define a frontier between our understanding of ... 
Submillimeter tests of the gravitational inversesquare law
(2001)The Newtonian Law of Universal Gravitation states that the strength of the gravitational force between point test bodies falls as the inversesquare of the distance between them. Recently, novel new theoretical scenario, ... 
Superkamiokande atmospheric neutrino analysis of matterdependent neutrino oscillation models
(2006)Current data finds that the atmospheric neutrino anomaly is best explained with numu  nutau neutrino oscillations. However, there is motivation for the Mass Varying Neutrino (MaVaN) model as an explanation for the presence ... 
Systematic Azimuth Quadrupole and Minijet Trends from TwoParticle Correlations in HeavyIon Collisions
(20140224)Heavyion collisions at the Relativistic Heavy Ion Collider (RHIC) produce a tremendous amount of data but new techniques are necessary for a comprehensive understanding of the physics behind these collisions. We present ... 
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 ... 
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 ...
