Query: Path-integral Monte Carlo simulation of time-reversal noninvariant bulk
  systems with a case study of rotating Yukawa gases   We elaborate on the methodology to simulate bulk systems in the absence of
time-reversal symmetry by the phase-fixed path-integral Monte Carlo method
under (possibly twisted) periodic boundary conditions. Such systems include
two-dimensional electrons in the quantum Hall regime and rotating ultracold
Bose and Fermi gases; time-reversal symmetry is broken by an external magnetic
field and the Coriolis force, respectively. We provide closed-form expressions
in terms of Jacobi elliptic functions for the thermal density matrix (or the
Euclidean propagator) of a single particle on a flat torus under very general
conditions. We then modify the multi-slice sampling method in order to sample
paths by the magnitude of the complex-valued thermal density matrix. Finally,
we demonstrate that these inventions let us study the vortex melting process of
a two-dimensional Yukawa gas in terms of the de Boer interaction strength
parameter, temperature, and rotation (Coriolis force). The bosonic case is
relevant to ultracold Fermi-Fermi mixtures of widely different masses under
rotation.
