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 ...
INVESTIGATING [X/FE], IMF AND COMPOSITENESS IN INTEGRATED MODELS
This dissertation explores several existing challenges of evolutionarystellar population synthesis models in integrated light:age-metallicity degeneracy, initial mass function (IMF), elementalabundances, and compositeness. ...
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 ...
Optical Imaging of Neural and Hemodynamic Brain Activity
Optical imaging technologies can be used to record neural and hemodynamic activity. Neural activity elicits physiological changes that alter the optical tissue properties. Specifically, changes in polarized light are ...
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, ...
Core versus peripheral positions: An integrated model
The notion of core versus peripheral entities can be found in a variety of disciplines. Common among various conceptualizations of core versus peripheral entities is the differentiation of power among countries, industries, ...
