Obtaining 1D dynamics in a quasi-1D NMR spin system
(Massachusetts Institute of Technology, 2008)In this thesis, I explored the evolution and dynamics of multiple quantum coherences in a quasi-iD crystal lattice, Fluorapatite (FAp), through the use of NMR. In particular I focused on the system with chains aligned with ... -
The Omniscope : mapping the Universe in 3D with neutral hydrogen
(Massachusetts Institute of Technology, 2011)21 cm tomography has the potential to become the most powerful cosmological probe yet. The Omniscope is a novel radio telescope being built to take advantage of this signal. This thesis describes my work on integrating, ... -
On the design of single electron transistors for the measurement of spins in phosphorus doped silicon
(Massachusetts Institute of Technology, 2012)Phosphorus doped silicon is a prime candidate for spin based qubits. We plan to investigate a novel hybrid technique that combines the advantages of spin selective optical excitations with that of electrical readout ... -
On the nature of electrified clouds that create positively polarized cloud-to-ground lightning and their link to sprites
(Massachusetts Institute of Technology, 1998) -
One fine wave demonstration device

An optical accordion trap for two-dimensional ultracold gases of ⁶Li and ²³Na
(Massachusetts Institute of Technology, 2019)An optical accordion trap is an optical lattice with a variable periodicity. By loading ultracold gases into a node of an accordion trap and then decreasing the lattice spacing, we plan to compress three dimensional ultracold ... -
Optical detection and analysis of Pictor A's jet
(Massachusetts Institute of Technology, 2014)New images from the Hubble Space Telescope of the FRII radio galaxy Pictor A reveal a number of jet knot candidates which coincide with previously detected radio and x-ray knots. Previous observations in x-ray and radio ... -
Optical detection development for the Hogan quantum holographic noise experiment
(Massachusetts Institute of Technology, 2010)Craig Hogan recently proposed a "quantum holographic" noise that could potentially raise the expected noise floor for some current and upcoming high precision interferometers. Rainer Weiss et al. have designed an experiment ... -
Optical imaging of Rydberg atoms
(Massachusetts Institute of Technology, 2012)We present an experiment exploring electromagnetically induced transparency (EIT) in Rydberg atoms in order to observe optical nonlinearities at the single photon level. ⁸⁷Rb atoms are trapped and cooled using a magneto-optical ... -
Optimization of a microwave resonator cavity to perform electron spin resonance measurements on quantum dots
(Massachusetts Institute of Technology, 2006)This thesis attempts to improve on an ongoing experiment of detecting electron spin resonance (ESR) on AlGaAs/GaAs lateral quantum dots. The experiment is performed in a 2.5 Tesla magnetic field at temperatures around ... -
Optimization of superconducting magnetic bearings using finite element modeling
(Massachusetts Institute of Technology, 2009)This project investigated the possibility of using superconducting bearings in large (3 - 100 MW) electric drives. Superconducting bearings are used to levitate the rotors inside electric drives via the Meiissner effect, ... -
Optimizing tensor contractions for nuclear correlation functions
(Massachusetts Institute of Technology, 2014)Nuclear correlation functions reveal interesting physical properties of atomic nuclei, including ground state energies and scattering potentials. However, calculating their values is computationally intensive due to the ... -
Orbital decay of hot Jupiters : coefficients of nonlinear tidal coupling as a function of the stellar host type
(Massachusetts Institute of Technology, 2016)Hot Jupiters raise strong tides in their host stars due to their large masses (around a Jupiter mass) and tight orbits (orbital periods P </~ 3 days). These tides remove orbital energy and angular momentum, causing the ... -
Orientation of gamma-ray telescope

Parameters affecting the spatial resolution of a superconducting solenoid
(Massachusetts Institute of Technology, 1978) -
Particle detector optimization via particle flow algorithms
(Massachusetts Institute of Technology, 2008)Using the the SLIC simulator software and the org.lcsim reconstruction framework package, the performance of Mat Charles' NonTrivialPfa.java PFA for several different detector variations was found by determining the mass ... -
Passive damping of a LIGO mirror
(Massachusetts Institute of Technology, 2009)There may be largely untapped source of information about our cosmic surroundings in the form of gravitational radiation, predicted by Einstein's theory of General Relativity. If detected, gravitational waves (GWs) could ... -
Path integrals and the quantum Routhian
(Massachusetts Institute of Technology, 2004)In this thesis, we consider the use of the Routhian in quantum mechanics, which is an object halfway between a Lagrangian and a Hamiltonian expressing the dynamics of a system in terms of conserved momentum and non-cyclic ... -
The penning trap electron gun for the KATRIN experiment
(Massachusetts Institute of Technology, 2008)The KArlsruhe TRitium Neutrino experiment (KATRIN) is currently in under construction, with plans to be activated in 2010. The experiment will measure the energy of electrons recoiling from the three body beta decay of ... -
Performance of drift tubes under high radiation
(Massachusetts Institute of Technology, 2005)In this thesis, the aging and the rejuvenation of an ATLAS proportional drift tube are described. Firstly, the Diethorn model of gain is tested using pressure and sense-wire voltage measurements. The drift tube was then ...
