Polarized fermions in one dimension: density and polarization from complex Langevin calculations, perturbation theory, and the virial expansion

26 Apr 2018 Loheac Andrew C. Braun Jens Drut Joaquín E.

We calculate the finite-temperature density and polarization equations of state of one-dimensional fermions with a zero-range interaction, considering both attractive and repulsive regimes. In the path-integral formulation of the grand-canonical ensemble, a finite chemical potential asymmetry makes these systems intractable for standard Monte Carlo approaches due to the sign problem...
