Half-Quantum Vortices in Nematic and Chiral Phases of He
Robert C. Regan, Joshua J. Wiman, J. A. Sauls
We report theoretical results for the stability of half-quantum vortices (HQVs) in the superfluid phases of He confined in highly anisotropic Nafen aerogel. Superfluidity of $^…
The Vortex Phase Diagram of Rotating Superfluid He-B
Robert C. Regan, J. J. Wiman, J. A. Sauls
We present the first theoretical calculation of the pressure-temperature-field phase diagram for the vortex phases of rotating superfluid He-B. Based on a strong-coupling exten…
Spontaneous helical order of a chiral p-wave superfluid confined in nano-scale channels
J. J. Wiman, J. A. Sauls
Strong interactions that favor chiral p-wave pairing, combined with strong pair breaking by confining boundaries, are shown to lead to new equilibrium states with different broken…
Strong-coupling and the Stripe phase of He
Joshua J. Wiman, J. A. Sauls
Thin films of superfluid 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…
