Inhomogeneous phases in one-dimensional mass- and spin-imbalanced Fermi gases
Dietrich Roscher, Jens Braun, Joaquín E. Drut
We compute the phase diagram of strongly interacting fermions in one dimension at finite temperature, with mass and spin imbalance. By including the possibility of the existence of…

Fermi gases with imaginary mass imbalance and the sign problem in Monte Carlo calculations
Dietrich Roscher, Jens Braun, Jiunn-Wei Chen +1
Fermi gases in strongly coupled regimes, such as the unitary limit, are inherently challenging for many-body methods. Although much progress has been made with purely analytic meth…
