Unusual Mechanism of Vortex Viscosity Generated by Mixed Normal Modes in Superconductors with Broken Time Reversal SymmetryThe Physical Review B (2013)
AbstractWe show that under certain conditions, multiband superconductors with broken time reversal symmetry have a vortex viscosity-generating mechanism which is different from that in conventional superconductors. It appears due to the existence of a mixed superfluid phase-density mode inside the vortex core. This contribution is dominant near the time reversal symmetry-breaking phase transition. The results could be relevant for the three-band superconductor Ba1−xKxFe2As2.
