Fairly little is known from a fundamental first principles level about the role of magnetism at material interfaces. This thesis will address (a) changes in spin density at grain boundaries and surfaces; (b) the impact of ...

There had been long-standing fundamental problems in the spectral studies of accreting neutron stars (NSs) in low-mass X-ray binaries involving the X-ray spectral decomposition, the relations between subtypes (mainly atoll ...

I analyze new phenomena arising from embedding active materials inside of photonic crystal structures. These structures strongly modify the photonic local density of states (LDOS), leading to quantitative and qualitative ...

16 years and counting ... In 1986 Bednorz and Muller discovered the layered perovskite structure (La - Ba)2Cu04 which showed the phenomenon of superconductivity at the unprecedented high temperature of Tc = 33 K. In the ...

The search for and the study of flavor oscillations in the neutral B,B, meson system is an experimentally challenging endeavor. This constitutes a flagship analysis of the Tevatron proton-antiproton collider physics program. ...

This Thesis considers the scenario in which an extra-solar planet (exoplanet) passes in front of its star relative to our observing perspective. In this event, the light curve measured for the host star features a systematic ...
