Precision Measurements with Rydberg States of Rubidium
(2019)
Rydberg atoms can be excellent tools for precision metrology thanks to their long lifetimes and interactions with external fields and other atoms that scale with large powers of the principal quantum number. In this thesis ...
New Methods for Terahertz and Ultrafast Infrared Spectroscopy of Biological Materials and Graphene Buffer Layer
(2019)
The development of advanced optical spectroscopy has always been a frontier in optics and material science. This dissertation develops several new methods for terahertz (THz) and infrared spectroscopy and presents their ...
Collisionless Shock Acceleration of Ions in Underdense Plasma
(2019)
This thesis contains experimental measurements of ions accelerated by electrostatic collision- less shockwaves within hot, laser produced plasma. This work contains new measurements of the shock-ion acceleration process ...
A Measurement of the Permanent Electric Dipole Moment of 129 Xe
(2019)
Searches for permanent electric dipole moments (EDMs) are a powerful way to investigate Beyond-the-Standard-Model CP-violation. This work describes the development of a new technique to measure the EDM of 129Xe with a 3He ...
First-Principles Calculations of Auger Recombination in Optoelectronic Materials
(2019)
Lighting currently uses around 15% of global energy expenditure. Reducing this energy usage would be an important part of reducing the effects of global climate change. LEDs (light-emitting diodes) could be a more efficient ...
Search for the Neutral Long-Lived Kaon Rare Decay KL -> pi0 nu nu-bar
(2019)
The goal of the KOTO experiment is to search for the direct CP violating decay mode, KL → π0νν, and to probe for physics beyond the Standard Model of the elementary particle physics by measuring the branching ratio of this ...
Theoretical and Experimental Study of Fuel Injector Tip Wetting as a Source of Particulate Emissions in Gasoline Direct-Injection Engines
(2019)
Gasoline fuel film deposited on the tip of a fuel injector, i.e. injector tip wetting, has been identified as a significant source of particulate emissions at some operating conditions of gasoline direct-injection engines. ...
Gravitational Waves From Spinning Neutron Stars: Development of a Directed Binary Search Technique and Spectral Characterization Tools
(2019)
Observational gravitational wave astronomy is a young field, begun in 2015 with the detection of the binary black hole merger event GW150914 by LIGO. Although all gravitational waves observed so far have emanated from the ...
