Vortical waves in a quantum fluid with vector, axial, and helical charges. I. Non-dissipative transport by Sergio Morales-Tejera, Victor E. Ambruş, Maxim N. Chernodub

“…The emergence of this wave can be traced back to earlier studies of vortical chiral fluids in a hydrodynamic approach. We also point out an unexpected instability in the limit of degenerate matter and discuss possible solutions when helicity and axial charge non-conservation are taken into account.…”
