Query: Superconductivity of doped Weyl semimetals: finite-momentum pairing and
  electronic analogues of the 3He-A phase   We study superconducting states of doped inversion-symmetric Weyl semimetals.
Specifically, we consider a lattice model realizing a Weyl semimetal with an
inversion symmetry and study the superconducting instability in the presence of
a short-ranged attractive interaction. With a phonon-mediated attractive
interaction, we find two competing states: a fully gapped finite-momentum
(FFLO) pairing state and a nodal even-parity pairing state. We show that, in a
BCS-type approximation, the finite-momentum pairing state is energetically
favored over the usual even-parity paired state and is robust against weak
disorder. Though energetically unfavorable, the even-parity pairing state
provides an electronic analogue of the 3He-A phase in that the nodes of the
even-parity state carry non-trivial winding numbers and therefore support a
surface flat band. We briefly discuss other possible superconducting states
that may be realized in Weyl semimetals.
