Abstract
Recently, we have developed an efficient recursive approach for analytically calculating the short-time expansion of the propagator to extremely high orders for a general many-body quantum system. Here we give brief overview of this approach and then demonstrate application of this technique by numerically studying the thermodynamical properties of a rotating ideal Bose gas of 87Rb atoms in an anharmonic trap. The obtained results improve previous semiclassical calculations and agree well with Path Integral Monte Carlo simulations.
