Exceeding the Landau speed limit with topological Bogoliubov Fermi surfaces
A common property of topological systems is the appearance of topologically protected zero-energy excitations. In a superconductor or superfluid, such states set the critical velocity of dissipationless flow v_{cL}, proposed by Landau, to zero. We check experimentally whether stable superflow is nev...
