Systems Other than Cold Atoms

Abstract

Although the bulk of this thesis concentrates on cold atomic gases, I have also worked in other areas of condensed matter physics. In graduate school, this has largely been in low temperature fluids and solids. The following chapters discuss some results I’ve obtained on these systems: collisional properties of nearly-degenerate spin-polarized hydrogen adsorbed on helium films (Chap. 16), anomalous behavior of atomic hydrogen defects in molecular hydrogen quantum solids (Chap. 17), and a possible scenario for supersolidity, inspired by experiments on solid hydrogen and helium (Chap. 18).
