Quantum Jump Spectroscopy of a Single Electron in a New and Improved ApparatusDorr, Joshua Charles 15 October 2013 (has links)
The 2008 measurement of the electron magnetic moment is the most precisely measured property of an elementary particle, with an astonishing precision of 0.28 parts per trillion. It makes possible the most precise determination of the fine structure constant and the most precise test of quantum electrodynamics and the Standard Model of particle physics. This thesis describes the installation of a new apparatus designed to have improved stability, more optimal control over the radiation field and inhibited spontaneous emission, and narrower resonance lines. / Physics

Quantum Optics and the Quantum Jump Technique for Lossy and Non-Orthogonal SystemsDoutre, Sean 28 September 2013 (has links)
In this thesis I develop a formalism for analyzing quantum optics in photonic crystal slab cavities
which may be coupled, lossy, and non-orthogonal. Using a tight-binding approximation I find classical
coupled-cavity quasimodes which overlap in space and frequency. These classical modes are
used to develop a multiphoton basis for quantum optics with non-orthogonal photon states. I develop
creation and annihilation operators with a novel commutation relation as a consequence of the nonorthogonality
of the quasimodes. With these operators the effective Hamiltonian, number operator,
electric field operator and quadrature operators are obtained.
The quantum jump technique is applied to handle the effects of loss. This technique is compared
with the master equation, and conditions for the quantum jump technique being preferable are
described. The quantum jump technique is implemented numerically, allowing for time-dependent
linear and X(2) non-linear pumping.
I use a combination of analytic results and characteristic functions to examine the evolution of
coherent and squeezed states in a single lossy quasimode. The analysis is then extended to two nonorthogonal
quasimodes. States are investigated using reduced characteristic functions. / Thesis (Master, Physics, Engineering Physics and Astronomy) -- Queen's University, 2013-09-27 12:00:10.281
