Measurement of the Z tau tau boson production cross-section in proton-proton collisions at sqrt(s) = TeV with the ATLAS detector
(2012-09-13)The first measurement of the inclusive cross-section of the <italic>Z</italic> boson decaying to two tau leptons was measured with the ATLAS detector at the LHC. The data sample in this analysis represents an integrated ... -
Measuring how lipid membranes respond to physical perturbations: How charge alters lipid miscibility, how shear disrupts interleaflet coupling, and how prebiotic compounds affect membrane stability
The physical and chemical properties of lipid bilayers determine their biological function as the main structural component of cell membranes. The response of lipid membranes to various perturbations is, in general, difficult ... -
Measuring the Mass of the W Boson with the Last 3.7 fb−1 of Tevatron Data.
This thesis presents the results of an analysis of the $3.7\,\textrm{fb}^{-1}$ of Tevatron proton-antiproton data collected with the DZero (D0) Detector at Fermilab during the ``RunIIb34'' period, with the goal of extracting ... -
Measuring the second harmonic amplitude of an oscillating torsion pendulum to detect small forces
(2000)After more than 200 years, the torsion balance/pendulum is still one of the most precise means for measuring weak, macroscopic-range forces. Historically, two primary measurement techniques have been developed for this ... -
Mechanisms of liquid crystal and biopolymer alignment on highly-oriented polymer thin films
(1998)Molecular order can strongly enhance material properties, or produce materials which perform advanced functions. Many materials, from small crystals to large macromolecules, may be aligned on highly-oriented poly(tetrafl ... -
Mixed Species Ion Chains for Scalable Quantum Computation
Mixed species chains of barium and ytterbium ions are investigated as a tool for building scalable quantum computation devices. Ytterbium ions provide a stable, environmentally-insensitive qubit that is easily initialized ... -
Molecular Effects in Tritium Beta-Decay Neutrino-Mass Measurements
An understanding of the molecular final state distribution is crucial to extracting a neutrino mass from molecular tritium-based experiments including the upcoming Karlsruhe Tritium Neutrino Mass Experiment. This dissertation ... -
Molecular Level Understanding of Interfaces and Excited State Electronic Structure in Organic Solar Cells Using Soft X-ray Techniques
(2013-11-14)Transparent conductive oxides like indium tin oxide (ITO) are common substrates for optoelectronic devices, including organic light emitting diodes and organic solar cells. Tailoring the interface between the oxide and the ... -
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 ... -
