Phase diagram and binding energy of interacting Bose gases
M. Männel, K. Morawetz, M. Schreiber +1
From the many-body T-matrix the condition for a medium-dependent bound state and its binding energy is derived for a homogeneous interacting Bose gas. This condition provides the c…

Intermittent relaxation in hierarchical energy landscapes
Andreas Fischer, Paolo Sibani, Karl Heinz Hoffmann
We numerically simulate a thermalization process in an energy landscape with hierarchically organized metastable states. The initial configuration is chosen to have a large energy…

Phase diagram for interacting Bose gases
K. Morawetz, M. Maennel, M. Schreiber
We propose a new form of the inversion method in terms of a selfenergy expansion to access the phase diagram of the Bose-Einstein transition. The dependence of the critical tempera…
