We review the concepts and the present state of theoretical studies of spin-imbalanced
superfluidity, in particular the elusive Fulde–Ferrell–Larkin–Ovchinnikov (FFLO) state, in the …

The interplay of strong interactions and magnetic fields gives rise to unusual forms of
superconductivity and magnetism in quantum many-body systems. Here, we present an …

The complexity of quantum many-body systems originates from the interplay of strong
interactions, quantum statistics, and the large number of quantum-mechanical degrees of …

Abstract The attractive Fermi–Hubbard model is the simplest theoretical model for studying
pairing and superconductivity of fermions on a lattice. It exhibits many interesting features …

Understanding if attractive fermions in an unbalanced occupation of its flavors can give rise
to a superfluid state in two dimensions (2D), realizing the Fulde-Ferrel-Larkin-Ovchinnikov …

We introduce a simple determinant diagrammatic Monte Carlo algorithm to compute the
ground-state properties of a particle interacting with a Fermi sea through a zero-range …

We use cellular dynamical mean-field theory with extended unit cells to study the ground
state of the two-dimensional repulsive Hubbard model at finite doping. We calculate the …

Leveraging cutting-edge numerical methodologies, we study the ground state of the two-
dimensional spin-polarized Fermi gas in an optical lattice. We focus on systems at high …

When a 2D superconductor is subjected to a strong in-plane magnetic field, Zeeman
polarization of the Fermi surface can give rise to inhomogeneous FFLO order with a spatially …

We calculate the pair susceptibility of an attractive spin-polarized Fermi gas in the normal
phase, as a function of the pair momentum. Close to unitarity, we find a strong enhancement …
