Bose-Einstein Condensation for Homogeneous Interacting Systems with a One-Particle Spectral Gap
J. Lauwers, A. Verbeure, V. A. Zagrebnov
We prove rigorously the occurrence of zero-mode Bose-Einstein condensation for a class of continuous homogeneous systems of boson particles with superstable interactions. This is t…
