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 ...

The axion is a hypothetical elementary particle resulting from a solution to the “Strong-CP” problem. This serious problem in the standard model of particle physics is manifested as a 10<super>10</super> discrepancy ...

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 mass-squared splittings governing neutrino oscillations ...

The Newtonian Law of Universal Gravitation states that the strength of the gravitational force between point test bodies falls as the inverse-square of the distance between them. Recently, novel new theoretical scenario, ...

Heavy-ion 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 ...

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. ...

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 ...

A single, trapped barium ion presents an excellent opportunity to make a precise atomic parity nonconservation measurement. The relatively perturbation-free single-ion trapping environment and high efficiency shelving ...

In this thesis, we present a theory of electron transport for unconventional superconductors. We focus on the superconducting properties of Sr₂RuO₄, which is a strong candidate for two dimensional ...

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 ...
