Pairing superfluidty in a Weyl semimetal with dipolar interaction

We study the topological superfluid phase of a three-dimensional Weyl semimetal realized in a single-component dipolar Fermi gas. The system is constructed by employing both the nearest and second-nearest hopping, and generating periodic gauge potentials in an anisotropic cubic lattice. By calculating the superfluid pairing induced by dipole-dipole interaction, we determine the phase diagram of this system and obtained many novel properties.
