Multi-Hadron Observables from Lattice Quantum Chromodynamics
We describe formal work that relates the finite-volume spectrum in a quantum field theory to scattering and decay amplitudes. This is of particular relevance to numerical calculations performed using Lattice Quantum ... -
The multichromatic wavelet transformation as a source identification tool for GLAST
(2004)The GLAST mission (Gamma-ray Large Area Space Telescope) will yield a great amount of photon data in the region from 30 MeV to 300 GeV. However, the sparsity of incoming photon events and strong dependence of instrument ... -
Multiphysics Simulation of Nanostructured Semiconductor Devices
(2014-02-24)This dissertation describes how to utilize multiphysics simulation techniques to develop physical (optics and device) models of nanostructured semiconductor devices. A hierarchy of approaches (ab-initio, continuum, ... -
Muon-Catalyzed Fusion Effects in the Precision Measurement of Muon Capture on the Deuteron
The MuSun experiment will measure the rate of muon capture on the deuteron to 1.5~\% precision. This reaction is related to solar $pp$ fusion and the $\nu d$ scattering reaction at the Sudbury Neutrino Observatory through ... -
The Murchison Widefield Array 21cm Epoch of Reionization Experiment: Design, Construction, and First Season Results
The Cosmic Dark Ages and the Epoch of Reionization (EoR) remain largely unexplored chapters in the history and evolution of the Universe. These periods hold the potential to inform our picture of the cosmos similar to what ... -
Nano-scale imaging and spectroscopy of plasmonic systems, thermal near-fields, and phase separation in complex oxides.
(2012-08-10)Optical spectroscopy represents a powerful characterization technique with the ability to directly interact with the electronic, spin, and lattice excitations in matter. In addition, through implementation of ultrafast ... -
Nanopore analysis of nucleic acids
(2007)Nanopore analysis of nucleic acids is a novel technique to study the physical properties of nucleic acids at the single-molecule level. It also has the potential to be a central component of a fundamentally new DNA sequencing ... -
Neutron electric dipole moment from QCD sum rules
(1996)The electric dipole moments of nucleons (NEDM, $d\sb{N}$) are calculated using the method of QCD sum rules. Our calculations are based on the parity ($/\!\!\!P$) and time reversal ($/\!\!\!T$) violating parameter $\bar\Theta$ ... -
New techniques and first results toward measuring the 6S(1/2) to 5D(3/2) magnetic-dipole transition moment in Ba+
We report the final results from our first-generation attempt to measure the magnetic-dipole transition moment (M1) between the $6S_{1/2}$ and $5D_{3/2}$ manifolds in Ba$^{+}$. Knowledge of M1 is crucial for a parity-non ... -
Non-Relativistic Holography from Horava Gravity
Holography is a powerful theoretical duality that relates quantum gravitational theories to non-gravitational theories in one less dimension. The most explored example of this tool is the correspondence between general ... -

A novel method for electron energy measurement: Cyclotron Radiation Emission Spectroscopy
A prototype spectrometer - the first of its kind - has been constructed at the University of Washington to demonstrate a new technique for β-decay studies called Cyclotron Radiation Emission Spectroscopy (CRES). The ... -
Nuclei as Probes of Meson-Nucleon Interactions at High and Low Energy
(2013-07-23)This dissertation explores two main topics: 1) Color Transparency and quasi-elastic knockout reactions involving pions and &rho mesons; and 2) determination of the J/&psi-nucleon scattering amplitude and scattering ... -
Observation of the Nuclear Magnetic Octupole Moment of 137Ba+
Single trapped ions are ideal systems in which to test atomic physics at high precision, which can in turn be used for searches for violations of fundamental symmetries and physics beyond the standard model, in addition ... -
On the Determination of Elastic and Inelastic Nuclear Observables from Lattice QCD
(2013-11-14)One of the overarching goals of nuclear physics is to rigorously compute properties of hadronic systems directly from the fundamental theory of the strong interaction, Quantum Chromodynamics (QCD). In particular, the hope ... -

Optical trapping of ytterbium atoms
(2003)This dissertation describes an experimental study on magneto-optical trapping (MOT) of ytterbium atoms. In particular, Doppler cooling and sub-Doppler cooling have been investigated and compared in the same atom, and ... -
Optoelectronic Properties of Two-Dimensional Materials
Layered materials when thinned down to their monolayer limit exhibit remarkable properties owing to their two-dimensional nature and strong electron confinement. In particular this class of materials displays strong optical ... -
The perturbative and non-perturbative QCD effects in the azimuthal distribution of hadron jets observed in muon deep inelastic scattering
(1997)Azimuthal asymmetry of hadron jets produced in deep inelastic muon scattering is studied for the first time. The data were collected at the experiment E665 at Fermilab during 1991-1992 using liquid hydrogen and deuterium ...
