Interacting Bosons at Finite Temperature: How Bogolubov Visited a Black Hole and Came Home Again
S. A. Fulling, B. -G. Englert, M. D. Pilloff
The structure of the thermal equilibrium state of a weakly interacting Bose gas is of current interest. We calculate the density matrix of that state in two ways. The most effectiv…

Statistics of dressed modes in a thermal state
Berthold-Georg Englert, Stephen A. Fulling, Mark D. Pilloff
By a Wigner-function calculation, we evaluate the trace of a certain Gaussian operator arising in the theory of a boson system subject to both finite temperature and (weak) interac…
