Description:
Author(s): Jan Gukelberger, Evgeny Kozik, Lode Pollet, Nikolay Prokof’ev, Manfred Sigrist, Boris Svistunov, and Matthias Troyer We study attractively interacting fermions on a square lattice with dispersion relations exhibiting strong spin-dependent anisotropy. The resulting Fermi surface mismatch suppresses the s-wave BCS-type instability, clearing the way for unconventional types of order. Unbiased sampling of the Feynman ... [Phys. Rev.
