The structure of hadrons and other potential phases of QCD
… (QCD) is a mathematical theory describing subatomic particles called quarks and gluons, and the strong force that binds them together into protons and neutrons. This thesis centers on two major thrusts of modern QCD research: (1) uncovering the inner quark and gluon structure of the proton, …

Confinement and Chiral Phase Transitions in SU(2) Gauge Theory via Topological Objects
… theory of the strong interaction between subatomic particles. A theoretical understanding of these transitions and their interrelations is of fundamental importance. While it is widely perceived that their dynamics arises from nontrivial topological configurations in Yang-Mills theories, a …

Search for supersymmetric partners of the top quark with the CMS detector and novel top quark tagging algorithms.
… in explaining observed interactions of subatomic particles. The model was largely vindicated with the announced observation of the Higgs boson by the ATLAS and CMS experiments at the LHC. The astronomical observation of dark matter, among other reasons, motivates us to look for particles …

The Many Scales of Quantum Fields and Gravity
… to the motion of planets or the dynamics of subatomic particles. Rather remarkably, understanding this seemingly elementary phenomenon led to one of the most profound paradigm shifts in Physics and to the most accurate agreement between theory and experiment in Science. All thanks to the …

Characterizing Non-Covalent Interactions And Peptide Bond Formation With Electronic Structure Theory
… that operates on the scale of atomic and subatomic particles. The advancement of quantum theory and computer technology has driven quantum mechanical analyses toward routine in the chemist's laboratory. Chapter 1 briefly outlines some comfailures of classical mechanics from a historical …

Novel X-Ray and Antinucleus Searches for Dark Matter
… density of the Universe resides in the familiar subatomic particles of the Standard Model. The remaining eighty percent is known as dark matter (DM), whose presence has so far only been inferred by its gravitational effects on SM particles at cosmic scales. This dissertation describes indirect …

Probing New Physics with Spectroscopy of Trapped Ions
… concerted experimental searches for candidate particles. In recent decades, experiments with atomic systems, driven by unprecedented developments in precision, have been providing tests for the Standard Model (SM), our current understanding of the Universe, and probing physics beyond the SM, …

Krylov Subspace Methods with Fixed Memory Requirements: Nearly Hermitian Linear Systems and Subspace Recycling
… chromodynamics, a theory of the behavior of subatomic particles. We wish to build on the class of Krylov methods which allow the simultaneous solution of all shifted linear systems while generating only one subspace. However, the mechanics of subspace recycling complicates this situation and …

High Angular Momentum Rydberg Wave Packets
High angular momentum Rydberg wave packets are studied. Application of carefully tailored electric fields to low angular momentum, high- n ( n ∼ 300) Rydberg atoms creates coherent superpositions of Stark states with near extreme values of angular momentum, [cursive l]. Wave packet components orbit …
