Excitons in cuprous oxide: high mobilities and strain confinement
… were bpatially confined in a strain-induced parabolic potential well where their thermodynamic properties and interparticle kinetics could be studied. Chapter 3 describes the technique used to measure the diffusion constant, D, and the drift mobility, 11, of paraexdtons, as well as a …

Diffusion, sub-diffusion, and escape: A study of over-damped Brownian motion
We study over-damped Brownian motion in various potential energy landscapes. Starting with one-dimensional systems, we derive the diffusion coefficient for motion in a piecewise-defined potential where the barrier height of each section is taken from a probability distribution. When the …

CONFINED ULTRACOLD BOSONS IN ONE DIMENSIONAL OPTICAL LATTICES
… properties of atoms in combined periodic and parabolic potentials are studied, with a focus on the strongly interacting regimes. Because parabolic magnetic and optical potentials are routinely used to confine atoms, the results of this research are directly relevant to ongoing experimental …

Design of a positron beam for the study of the entanglement in three gamma-rays generated by positronium annihilation
… which are accumulated in an electrostatic potential well along the magnet axis. When the positrons enter the trap, they are cooled by inelastic scattering with gas introduced into the chamber until they fall to the bottom of the potential well. The design of the PSICO BGT is based on a …
