Characterizing and Leveraging Students’ Conceptual Resources for Wave Mechanics
In its earliest days, a primary focus of physics education research was investigating common patterns of student reasoning about specific physics topics to inform instruction and curriculum development. This continues to ... -
Charge Symmetry Breaking and Nuclear Pion Production Reactions
(2011-08)Large momentum transfer reactions such as pion production represent the frontier of Chiral Perturbation Theory and must be understood before more complex reactions can be considered. Pion production is also interesting ... -
Chiral perturbation theory on the lattice and its applications
(2004)Chiral perturbation theory (chiPT), the low-energy effective theory of QCD, can be used to describe QCD observables in the low-energy region in a model-independent way. At any given order in the chiral expansion, chiPT ... -
Classical and Quantum Computation in Ground States and Beyond
In this dissertation we study classical and quantum spin systems with applications to the theory of computation. In particular, we examine computational aspects of these systems beyond their ground states by considering ... -
Compiling Quantum Gauge Theories for Quantum Computation
This dissertation gives a survey of formal issues of Hamiltonian lattice gauge theories in the context of simulation by quantum computers. The basic properties of gauge field theories and their lattice regularizations are ... -
Compton Scattering and Warm Dense Matter Thermometry
(2014-02-24)The purpose of this dissertation is to consider the level of detail required for proper theoretical description of non-resonant inelastic x-ray scattering (NIXS) experiments from warm dense matter (WDM). These experiments ... -
Computational Studies on Novel Atomic Force Microscopy Techniques and Plasmonic-Enhanced Organic Photovoltaics
In physical and life sciences, employing computational approaches to understand the nature of studied materials and subjects and to analyze immense amount of data is increasingly becoming more popular. Using existing methods ... -
Configuration mixing of quark states in nucleons and other baryons in the MIT bag model
(1997)The MIT bag model incorporates two of the main features of Quantum Chromodynamics (QCD), confinement of quarks in color singlet states, and asymptotic freedom. Most prior studies using this model have been perturbative, ... -
Constraining the Neutrino Mass Using Cyclotron Radiation Emission Spectroscopy
The existing prototype to demonstrate the viability of the Cyclotron Radiation Emission Spectroscopy (CRES) has been upgraded to incorporate tritium compatibility. The spectrum of the conversion electrons from $^{83m}Kr$ ... -
Control Theory for C. elegans Calcium Imaging Dynamics
This thesis contains several projects under two main headings: data-driven modeling, and C. elegans applications. Most of these works build to the main core of this thesis: applying novel control theoretic methods to C. ... -
Coupling the Radial Vibrational Modes of Mixed Barium-Ytterbium Chains for Quantum Computing
The advantages of mixed species ion chains may be essential to scaling a quantum computer; however, using them requires a better understanding of mixed species ion trapping and manipulation than we currently posses. In ... -
Dark Matter Particle Astrophysics: How Dark Matter Can Affect Subhalos, Neutrinos, and Neutron Stars
Predicted almost a century ago, dark matter explains many astrophysical observations including the motion of matter on galaxy and galaxy cluster scales, the clustering of galaxies, and the anisotropies in the cosmic microwave ... -
Data-Driven Methods for Physics-Constrained Dynamical Systems
As the availability of large data sets has risen and computation has become cheaper, the field of dynamical systems analysis has placed increased emphasis on data-driven numerical methods for diagnostics, forecasting, and ... -
Data-driven modeling and control of quantum dynamics
Control is the factor that delineates quantum science from quantum engineering. Model-based optimal control is a modern approach to practical control engineering. It designs control laws using optimization based on dynamical ... -
Deep Learning Applications for Particle Physics in Tracking and Calorimetry
This thesis presents an in-depth exploration of advanced deep learning applications in particle physics, particularly in the context of tracking, calorimetry, and energy reconstruction within High Energy Physics (HEP) ... -
Demonstration of trapped single laser cooled indium ions
(1995)Single Indium ions have been confined in a RF Paul-Straubel trap, positioned within an ultra high vacuum environment. Indium is a group IIIA atom and, in its singly ionized state, has a J = 0 $-$ J = 0 "clock" transition ... -
Design and Optimization of Dielectric Metasurface Optics
In recent years, sub-wavelength, aperiodic gratings, currently coined metasurfaces have the potential to manipulate electromagnetic elds with extreme control in a remarkably small form factor. These planar optical components ... -
Detecting new planets in transiting systems
(2006)I present an initial investigation into a new planet detection technique that uses the transit timing of a known, transiting planet. The transits of a solitary planet orbiting a star occur at equally spaced intervals in ... -
A Determination of the Mass of the Deuteron
(2012-08-10)We have measured the atomic mass of the deuteron relative to the calibration <super>12</super>C<super>6+</super> and <super>12</super>C<super>4+</super> ions and arrived at a value of 2 014 101 778 052 (40) pu for the ... -
Developing Laboratory-Based X-ray Spectroscopies for Energy and Materials Research spectroscopy
Advanced x-ray spectroscopies interrogate a material’s electronic structure in an element-specific manner. Traditionally, X-ray absorption fine structure (XAFS) and X-ray emission spectroscopy (XES) studies are performed ...
