This thesis describes the design, construction, and testing of a new source of entanglement. The goal is to produce pairs of photons which are not only polarization-entangled, but also have a high brightness within a narrow ...

This thesis presents results from experiments of ultracold atomic Fermi gases with repulsive interaction. Itinerant ferromagnetism was studied by simulating the Stoner model with a strongly interacting Fermi gas of ultracold ...

In this thesis, I explore three classes of quantum phases of matter that cannot be understood purely on the basis of symmetry, and can be regarded (to varying degrees) as having highly-entangled ground-states. The first ...

A complete, scalable prototype analysis system for the observation of gravitational wave bursts with a network of interferometric detectors is designed and tested. This system detects localized transients in the gravitational ...

Binary systems composed of compact objects (neutron stars and black holes) radiate gravitational waves (GWs). The prospect of detecting these GWs using ground and space based experiments has made it imperative to understand ...

This thesis presents three studies of warm (photoionized) absorber variability in Active Galactic Nuclei (AGN) using high-resolution X-ray spectra provided by the Chandra High Energy Transmission Grating (HETG). The first ...

This thesis comprises the results of two distinct areas of research, namely, X-ray studies of Galactic globular clusters and X-ray studies of recent core collapse supernovae. My analyses of the Chandra X-ray Observatory ...
