The evolution of an attractive polarized two-component Fermi gas at zero temperature is
analyzed as its polarization is progressively decreased, from full polarization (corresponding …

We study the nature of superfluid pairing in imbalanced Fermi mixtures in two spatial
dimensions. We present evidence that the combined effect of Fermi surface mismatch and …

Increasing the spin imbalance in superconductors can spatially modulate the gap by forming
Cooper pairs with finite momentum. For large imbalances compared to the Fermi energy, the …

We theoretically study a possible pairing mechanism for a two-dimensional population
imbalanced Fermi gas with short-range repulsive interactions, which can be realized on the …

All superconductors known so far exhibit pairing of electrons into a state with vanishing total
momentum. In the presence of a finite difference in the population of electrons with opposite …
