Fe-based superconductors (FeSC) exhibit all the properties of systems that allow the
formation of a superconducting phase with oscillating order parameter, called the Fulde …

We derive the effective Ginzburg-Landau (GL) theory for finite-momentum [Fulde-Ferrell-
Larkin-Ovchinnikov/pair-density wave (FFLO/PDW)] superconductivity without spin …

The theoretical analysis of the Cooper pair susceptibility shows the two-band Fe-based
superconductors (FeSC) to support the existence of the phase with nonzero Cooper pair …

The coexistence of antiferromagnetism with superconductivity is studied theoretically within
the tJ model with the Zeeman term included. The strong electron correlations are accounted …

We study the superconducting properties of population-imbalanced ultracold Fermi mixtures
in one-dimensional optical lattices that can be effectively described by the spin-imbalanced …

Within the renormalization-group framework we study the stability of superfluid density wave
states, known as Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) phases, with respect to thermal …

We present studies of the atomic limit of the extended Hubbard model with pair hopping for
arbitrary electron density and arbitrary chemical potential. The Hamiltonian consists of (i) the …

Iron based superconductors are characterized by the {{s}+/-} gap symmetry, where the gap
changes its sign between pockets of the Fermi surface. We discuss another sign change …

We study superconducting properties of population-imbalanced ultracold Fermi mixtures in
the honeycomb lattice that can be effectively described by the spin-imbalanced attractive …

Obtaining a thermodynamically accurate phase diagram through numerical calculations is a
computationally expensive problem that is crucially important to understanding the complex …
