Quantum thermodynamics near the border of a one-dimensional Bose gas
Carsten Henkel
We consider an ultracold Bose gas in a half-open potential well, otherwise confined to a quasi-one-dimensional geometry. The Bogoliubov equations for its elementary excitations are…

A comparison between microscopic methods for finite temperature Bose gases
S. P. Cockburn, A. Negretti, N. P. Proukakis +1
We analyze the equilibrium properties of a weakly interacting, trapped quasi-one-dimensional Bose gas at finite temperatures and compare different theoretical approaches. We focus…
