Suppression of superfluid stiffness near Lifshitz-point instability to finite momentum superconductivity
Jonatan Wårdh, Mats Granath, Brian M. Andersen
We derive the effective Ginzburg-Landau theory for finite momentum (FFLO/PDW) superconductivity without spin population imbalance from a model with local attraction and repulsive p…

Effective model for a supercurrent in a pair-density wave
Jonatan Wårdh, Mats Granath
We extend the standard effective model of d-wave superconductivity of a single band tight-binding Hamiltonian with nearest-neighbor attraction to include finite range periodically…

Pair production from residues of complex worldline instantons
Anton Ilderton, Greger Torgrimsson, Jonatan Wårdh
We study nonperturbative pair production in electric fields with lightlike inhomogeneities, using complex worldline instantons. We show that the instanton contribution to the pair…
