Finite Temperature Collapse of a Bose Gas with Attractive Interactions

Abstract

We study the mechanical stability of the weakly interacting Bose gas with attractive interactions, and construct a unified picture of the collapse valid from the low temperature condensed region to the high temperature classical regime. As we show, the non-condensed particles play a crucial role in determining the region of stability. We extend our results to describe domain formation in spinor condensates.
