Strong-coupling and the Stripe phase of ${}^3$He

Abstract

Thin films of superfluid ${}^3$He were predicted, based on weak-coupling BCS theory, to have a stable phase which spontaneously breaks translational symmetry in the plane of the film. This crystalline superfluid, or "stripe" phase, develops as a one dimensional periodic array of domain walls separating degenerate B phase domains. We report calculations of the phases and phase diagram for superfluid ${}^3$He in thin films using a strong-coupling Ginzburg-Landau theory that accurately reproduces the bulk ${}^3$He superfluid phase diagram. We find that the stability of the Stripe phase is diminished relative to the A phase, but the Stripe phase is stable in a large range of temperatures, pressures, confinement, and surface conditions.
