The Orbital Evolution of Planet-Disk Solar Systems.
(2008)
The extrasolar planets discovered to date possess larger eccentricities and smaller semi-major axes than similar planets in our solar system. It is not thought possible for these planets to form in situ; we propose they ...
Coherent Optical Spectroscopy of a Single Semiconductor Quantum Dot.
(2008)
The quantum optoelectronic properties of semiconductor quantum dots (QDs) have featured prominently in numerous scientific proposals,
including quantum computing, single photon sources, and spintronic devices. QDs are ...
Towards a Measurement of the Electric Dipole Moment of Rn.
(2009)
The observed baryon asymmetry in the universe requires a greater degree of CP
violation than is contained in the CP-violating Standard Model processes discovered
thus far. Since the permanent electric dipole moment (EDM) ...
Few-Cycle and Sub-Cycle Metrology for the Characterization of High Harmonics.
(2009)
The rapid advances in the generation of ultra-short optical pulses in recent decades have often outstripped the ability of metrologists to accurately measure the pulses' temporal profiles. With each reduction in pulse ...
Higgs Exempt No-Scale Supersymmetry.
(2009)
Models with acceptably small flavor changing neutral currents at the low scale require highly constrained scalar masses at the high scale. With all boundary masses small except the gauginos and Higgs bosons, the renormalization ...
String Theory Effects on Black Hole Physics
(2009)
This thesis focuses on recent developments in black hole physics in the context of string theory. The two main topics discussed here are: the effects of quantum/string corrections to five dimensional black holes; and the ...
Quantum Computing Over Long Time Scales in a Singly Charged Quantum Dot.
(2011)
In this thesis, we will study the continuous wave optical spectroscopy of self-assembled quantum dots (SAQDs), focusing on the use of these dots toward quantum computing and information processing applications. Probing the ...
Spin and Lattice Dynamics in Thin Films: From Femtoseconds to Nanoseconds.
(2010)
In this dissertation we set out to quantitatively investigate the dynamics of magnetic thin films. Specifically, we studied the spin dynamics in epitaxial metallic ferromagnets and the coupling to other degrees of freedom, ...
Modeling R8 Specification in the Drosophila Eye, from Genes to Tissue.
(2011)
Drosophila melanogaster, the fruit fly, has compound eyes consisting of around 750 facets called ommatidia, arranged in a regular hexagonal grid. Each facet is centered on a suite of 8 photoreceptor neurons (R1-R8), of ...
From structure to dynamics and back: The interplay between topology and activity in brain networks.
(2011)
The brain is an enormously complex network of neurons and supporting cells. The topological structure of these neuronal networks form the basis for learning, memory, cognition, and every other function. In return, those ...
