Improving Imaging Resolution For In-Situ Measurements of Bose-Einstein Condensates
A 85Rb Bose-Einstein Condensate (BEC) is an ideal experimental tool for studying strongly interacting quantum many-body systems. In our experiment we measure the size of the BEC by analyzing images of the BEC. Unfortunately our current imaging resolution limits our ability to make accurate measurements of the BEC size in-situ. In this thesis I will describe my work to improve the imaging resolution of our experimental system, which resulted in the implementation and testing of a new and improved imaging system. I will also outline some of the novel physics we plan to investigate with the new capability to accurately image the BEC in-situ

Matter Unification in Warped Supersymmetric SO(10)
We construct models of warped unification with a bulk SO(10) gauge symmetry
and boundary conditions that preserve the SU(4)_C x SU(2)_L x SU(2)_R
Pati-Salam gauge group (422). In the dual 4D description, these models are 422
gauge theories in which the apparent unification of gauge couplings in the
minimal supersymmetric standard model is explained as a consequence of strong
coupling in the ultraviolet. The weakness of the gauge couplings at low
energies is ensured in this 4D picture by asymptotically non-free contributions
from the conformal sector, which are universal due to an approximate SO(10)
global symmetry. The 422 gauge symmetry is broken to the standard model group
by a simple set of Higgs fields. An advantage of this setup relative to SU(5)
models of warped unification is that matter is automatically required to fill
out representations of 422, providing an elegant understanding of the quantum
numbers of the standard-model quarks and leptons. The models also naturally
incorporate the see-saw mechanism for neutrino masses and bottom-tau
unification. Finally, they predict a rich spectrum of exotic particles near the
TeV scale, including states with different quantum numbers than those that
appear in SU(5) models.Comment: 19 pages, Latex, version to appear in Nucl. Phys.
Cardiovascular dynamics during space sickness and deconditioning
We are currently funded by NASA for the project, 'Cardiovascular Dynamics During Space Sickness and Deconditioning.' NASA has given priority to the investigation of two problems encountered in the long-term space flights currently being planned: (1) space motion sickness; and (2) cardiovascular deconditioning. We have proposed to use spectral and nonlinear dynamical analysis of heart rate data to quantify the presence of these problems and to evaluate countermeasures against them
Spectrum of TeV Particles in Warped Supersymmetric Grand Unification
In warped supersymmetric grand unification, XY gauge particles appear near
the TeV scale along with Kaluza-Klein towers of the standard model gauge
fields. In spite of this exotic low-energy physics, MSSM gauge coupling
unification is preserved and proton decay is naturally suppressed. In this
paper we study in detail the low-lying mass spectrum of superparticles and GUT
particles in this theory, taking supersymmetry breaking to be localized to the
TeV brane. The masses of the MSSM particles, Kaluza-Klein modes, and XY states
are all determined by two parameters, one which fixes the strength of the
supersymmetry breaking and the other which sets the scale of the infrared
brane. A particularly interesting result is that for relatively strong
supersymmetry breaking, the XY gauginos and the lowest Kaluza-Klein excitations
of the MSSM gauginos may both lie within reach of the LHC, providing the
possibility that the underlying unified gauge symmetry and the enhanced N=2
supersymmetry of the theory will both be revealed.Comment: 29 pages, 5 figure
