Spin-Photon Entanglement and Quantum Optics with Single Quantum Dots.
(2013)
InAs quantum dots (QDs) can be used as optically coupled quantum storage devices for quantum information applications. The QD can be charged with a single electron, where the spin state (up or down) provides a long lived ...
Laser-ion acceleration through controlled surface contamination
(The American Institute of Physics, 2011-04)
Disentanglement and decoherence without dissipation at non-zero temperatures
(2010-09)
Decoherence is well understood, in contrast with disentanglement. According to common lore, irreversible coupling to a dissipative environment is the mechanism for loss of entanglement. Here, we show that, on the contrary, ...
Sharpening Our Observational Tools to Nail Down the Nature of Dark Energy.
(2016)
This dissertation investigates systematic effects and performs new cosmological tests with observational probes of dark energy in anticipation of the precision dark energy constraints expected in the near future. Chapters ...
Effects of Random Manufacturing Errors on the Performance of Contemporary Coherent Radiation Sources.
(2014)
The traveling wave tube (TWT) is a linear beam microwave vacuum electron device (MVED) and is a key element in telecommunication systems, satellite-based transmitters, military radar, electronic countermeasures, and ...
What Turns Galaxies Off? The Different Morphologies of Star-forming and Quiescent Galaxies since z ~ 2 from CANDELS
(IOP Publishing, 2012)
We use HST /WFC3 imaging from the CANDELS Multi-Cycle Treasury Survey, in conjunction with the Sloan Digital Sky Survey, to explore the evolution of galactic structure for galaxies with stellar masses >3 √ó 10 10 M ...
A doublet microlens array for imaging micron-sized objects
(IOP Publishing, 2011)
We present a high-numerical aperture, doublet microlens array for imaging micron-sized objects. The proposed doublet architecture consists of glass microspheres trapped on a predefined array of silicon microholes and covered ...
Oblique radiative shocks, including their interactions with nonradiative polytropic shocks
(The American Institute of Physics, 2011-05)
Ratcheting Up The Search For Dark Matter.
(2014)
The last several years have included remarkable advances in two of the primary areas of fundamental particle physics: the search for dark matter and the discovery of the Higgs boson. This dissertation will highlight some ...
Fluorescent and lasing whispering gallery mode microresonators for sensing applications
(Springer International PublishingWiley Periodicals, Inc., 2017-03)
Whispering gallery modes (WGMs) have been exploited for a broad range of sensing applications. However, the vast majority of WGM sensors consist of passive resonators, requiring complex interrogation systems to be employed, ...
