Atomic Jump Frequencies in Intermetallic Compounds Studied Using Perturbed Angular Correlation of Gamma Rays
Atomic jump frequencies were determined in a variety of intermetallic compounds through analysis of nuclear relaxation of spectra measured using the nuclear hyperfine technique, perturbed angular correlation (PAC) of gamma ...
Large volume single crystal growth of Cadmium Zinc Telluride with minimal secondary phases for room temperature radiation detector application
Two major aspects of Cadmium Zinc Telluride (CdZnTe) crystal growth for room temperature radiation detection application namely tellurium rich second phase defects and single crystal yield have been addressed. Various ...
MULTI-BASELINE SEARCHES FOR STOCHASTIC SOURCES AND BLACK HOLE RINGDOWN SIGNALS IN LIGO-VIRGO DATA
We present a framework for the detection of stochastic gravitational-wave (GW) backgrounds, from cosmological and astrophysical sources, using radiometry with a network of gravitational-wave interferometers. The search ...
EXCIMER LASER INTERACTION WITH ZINC OXIDE
When single crystal ZnO is exposed to 193-nm laser photons in vacuum at fluences below 100 mJ/cm
DEFECTS IN ZINC OXIDE NANOCRYSTALS
Defects in ZnO nanocrystals were investigated. While ZnO has potential for optoelectronic applications, the lack reliable p-type doping remains a major challenge. We provide evidence that ZnO nanocrystals contain uncompensated ...
Explicitly Correlated Gaussian Approach: Method Development and Application to Ultracold Few-Fermion Systems
Few-body physics plays an important role in quantum gases. For example, the lifetime of ultracold atomic gases is limited by atom losses. While atom losses are, in general, undesirable, they can be measured experimentally ...
Understanding Molecular Machines: Theoretical and Experimental Approaches
This dissertation concerns the study of two classes of molecular machines from a physical perspective: enzymes and membrane proteins. Though the functions of these classes of proteins are different, they each represent ...
ULTRAFAST SPECTROSCOPY OF SELF TRAPPED EXCITONS IN QUASI-ONE-DIMENSIONAL MATERIALS
This dissertation studies the transition of electronic excitations from a delocalized state to a localized state. Such processes have a dramatic impact on optical and electronic properties and reflect fundamental interactions ...
MEAN-FIELD STUDIES OF DIPOLAR BOSE-EINSTEIN CONDENSATES
The behavior of polarized dipolar Bose-Einstein condensates (BECs) in a harmonic trap has been extensively studied in the mean-field approximation. Mean-field studies show that, in contrast to $s$-wave interacting BECs, ...
EFFECT OF LOADING RATE AND PEAK STRESS ON THE ELASTIC LIMIT OF DYNAMICALLY COMPRESSED BRITTLE SINGLE CRYSTALS
To examine the effect of loading rate on the compressive elastic limit of brittle solids, shockless and shock compression experiments were conducted on x-cut and z-cut quartz crystals. A compact pulsed power generator was ...
