Dissipative dynamics of atomic Bose-Einstein condensates at zero temperature
(2013-04-26)In this thesis we study various dissipative processes that are associated with the flow of an atomic Bose-Einstein condensate at zero temperature. In particular, we investigate the effect of a weak correlated disorder ... -
Domain Boundaries of the 5x5 DAS Reconstruction
(2011-11-11)Steps on surfaces have long been explored for their own sake, and exploited as growth mediators. However, another type of linear surface defect - the domain boundary - has been largely neglected. Here we introduce domain ... -
Dust Dynamics in the Galactic Disk-Halo Vicinity
(2007-09-27)We report on the dynamics of interstellar dust grains above the plane of the Milky Way. Our Galactic model closely matches its large-scale observed properties, namely the luminosity output, the gas content and distribution, ... -
Dyadic Green Functions and their applications in Classical and Quantum Nanophotonics
(2012-04-26)Research in solid-state nanophotonics and quantum optics has been recently pushing the limits in semiconductor microcavity design. High quality microcavities that confine light into small volumes are now able to drastically ... -
Dynamic Made-To-Measure: A Method of Making Dynamically Self-Consistent Triaxial Dark Matter Halos
(2010-04-14)In this thesis we modify the Made-To-Measure (M2M) algorithm to be dynamically selfconsistent and apply it to the problem of generating equilibrium collisionless systems with non-spherical halos. Our M2M algorithm ... -
Dynamical Evolution and Growth of Protoplanets Embedded in a Turbulent Gas Disk
(2009-09-17)Simulations were performed to determine the effect of turbulence on protoplanets as they accrete inside of a planetary gas disk at the stage of planet formation that involves interactions between relatively large, similar ... -
The Dynamical Properties of Virgo Cluster Galaxies
(2013-01-04)By virtue of its proximity, the Virgo Cluster is an ideal laboratory for us to test our understanding of the formation of structure in our Universe. In this spirit, we present a dynamical study of 33 gas-poor and 34 gas-rich ... -
Dynamics of Bose-Einstein Condensates in Josephson Junctions
(2011-01-11)We numerically solve the Gross-Pitaevskii equation and the Bogoliubov de Gennes equations for a double well potential in order to model the dynamics of a Bose-Einstein condensate in a Josephson junction. First, the two ... -
The Dynamics of Quantum States of Light in Lossy Coupled-Cavity Systems
Nonclassical states of light possess unique properties such as squeezing, antibunching, and entanglement, which have led to various interesting applications in quantum computing, quantum teleportation, and quantum ... -
Early development of a test-bed to measure fractoluminescence in scintillators & simulation of a Na-24 source for the SNO+ experiment
(2014-06-24)This thesis consists of two parts; the first part pertains to fractoluminescence as a potential background in crystal scintillator detectors, and the second part bears on the simulation of a 24Na source to be used during ... -
The Effect of Disorder on Strongly Correlated Electrons
(2011-08-31)This thesis is devoted to a study of the effect of disorder on strongly correlated electrons. For non-interacting electrons, Anderson localization occurs if the amount of disorder is sufficient. For disorder-free systems, ... -
Effect of Encapsulation and Light-Soaking on Charge Transport Properties in Organic Semiconductor-Based Diodes
Organic semiconductors (OSs) are gaining attention due to their processability, optical and electrical tunability, and cost-effectiveness. This class of materials is most suitable for flexible electronics and bioelectronics, ... -
The Effects of Fractal Molecular Clouds on the Dynamical Evolution of Oort Cloud Comets
(2009-09-23)The Oort Cloud (OC) is a roughly spherical cloud of comets surrounding the solar system, stretching from well beyond the orbit of Neptune, half way to the nearest star. This body of comets is interesting because it ... -
The Effects of Multi-exciton Interactions on Optical Cavity Emission
(2012-07-31)This thesis presents a theoretical study of the collective effects of a large number of photon emitters coupled to optical cavities. The ensemble effects are accounted for by considering both the light emitting and ... -
Electrical and Optical Probing of Extremely Large Planar Polymer Light-Emitting Electrochemical Cells
(2011-05-13)Polymer light-emitting electrochemical cells (LECs) are unique solid-state light-emitting devices operating on the principle of in situ electrochemical doping and the formation of a p-n junction. Compared to conventional ... -
