Progress towards high precision measurements on ultracold metastable hydrogen and trapping deuterium
(cont.) not achieve deuterium trapping through helium-surface cooling. It is proposed that buffer gas loading can be used to cryogenically cool and trap deuterium.

Effects of dissipative environments on some quantum systems
… ring, the escape rate of an electron from a helium surface, and the transition probability of the Landau-Zener level crossing. Chapter one contains a general introduction to these physical systems and a brief review of the theoretical methods I shall use. The study of an equilibrium property, …

Low Density 2D-Electron Sheets on Liquid 3He Surfaces
… work, experiments with electron mobility on the surface of 3He were carried out. Mobility measurements were done in the temperature range 0.6-600mK, the operating frequencies 1Hz-100kHz, the excitation voltage 4mV - 1V and pressing electrical fields 0-255V/cm on the top electrode and 0-47.5V/cm …

Path Integral Monte Carlo Simulations of Helium: From Superfluid Droplets to Quantum Crystals
… are manifested in microscopic, inhomogeneous helium systems. Path Integral Monte Carlo is a powerful method for calculating the equilibrium properties of quantum systems at finite temperature. We have achieved linear scaling of computer time with number of particles through the use of neighbor …
