Odd Parity Transport In Non-Abelian Superfluids From Symmetry Locking

Understand

We consider relativistic non-Abelian superfluids, where the expectation value of the global symmetry currents relate space and internal indices, thus creating a "locked" phase.

• Locking a superfluid with SU(2) internal symmetry in 2+1 dimensions breaks parity spontaneously, and introduces parity-odd terms in the constitutive relations.
• We show that there are qualitatively different extensions of the rest frame locking to non-zero velocities.
• We construct the resulting superfluid hydrodynamics up to the first derivative order.
