Thermal activation of superconducting Josephson junctions
(Massachusetts Institute of Technology, 2007)
Superconducting quantum circuits (SQCs) are being explored as model systems for scalable quantum computing architectures. Josephson junctions are extensively used in superconducting quantum interference devices (SQUIDs) ...
Loading rubidium atoms into a hollow core fiber
(Massachusetts Institute of Technology, 2007)
We demonstrate a procedure for cooling, trapping, and transferring rubidium atoms into a hollow core photonic band gap fiber. The atoms are first collected in a magneto-optical trap (MOT) and then cooled using polarization ...
Trapping cold rubidium in a fiber
(Massachusetts Institute of Technology, 2007)
In this thesis, we demonstrate the novel technique of loading cold ⁸⁷Rb into a red-detuned optical dipole trap within a hollow core photonic fiber. This confines the atoms to 6 microns in two dimensions. We initially cooled ...
Self-assembly of conformal polymer electrolyte film for lithium ion microbatteries
(Massachusetts Institute of Technology, 2007)
I apply the theory of polar and apolar intermolecular interactions to predict the behavior of combinations of common battery materials, specifically the cathode substrate lithium cobalt oxide (LCO) and the polymer separator ...
Signal variation in single particle aerosol mass spectrometry
(Massachusetts Institute of Technology, 2007)
Rapid and accurate detection of airborne micro-particles is currently an important problem in national security. One approach to such detection, bioaerosol mass spectrometry (BAMS), is currently under development at Lawrence ...
Charged multiplicity measurement for simulated pp events in the Compact Muon Solenoid (CMS) detector
(Massachusetts Institute of Technology, 2007)
In this thesis, I studied the effectiveness of a method for measuring the charged multiplicity of proton-proton collisions in the Compact Muon Solenoid (CMS) experiment at LHC energies ... This technique involves counting ...
Velocity-ion temperature gradient driven modes and angular momentum transport in magnetically confined plasmas
(Massachusetts Institute of Technology, 2007)
Plasma confinement experiments continue to uncover fascinating phenomena that motivate theoretical discussion and exploration. In this thesis, we consider the phenomenon of angular momentum transport in magnetically confined ...
Synthesis of electromagnetic modes in photonic band gap fibers
(Massachusetts Institute of Technology, 2007)
In this paper, we report on the successful synthesis of three individual modes, HE11, TEo0, and TE02 for transmission in photonic band gap fibers at near infrared wavelengths. We measure the propagation losses of the HE11 ...
High-temperature superfluidity in an ultracold Fermi gas
(Massachusetts Institute of Technology, 2007)
This thesis presents experiments in which a strongly interacting gas of fermions was brought into the superfluid regime. The strong interactions are induced by a Feshbach scattering resonance that allows to tune the ...
Magnetic reconnection in high-temperature plasmas : excitation of the drift-tearing mode and the transport of electron thermal energy
(Massachusetts Institute of Technology, 2007)
The problem of excitation of the drift-tearing mode (Coppi, 1964) in high-temperature plasmas is considered. Existing theories predict that under the conditions typical of modern toroidal experiments on nuclear fusion, the ...
