Topological Waves in Fluids with Odd Viscosity
Topological Waves in Fluids with Odd Viscosity
Fluids in which both time reversal and parity are broken can display a dissipationless viscosity that is odd under each of these symmetries. Here, we show how this odd viscosity has a dramatic effect on topological sound waves in fluids, including the number and spatial profile of topological edge modes. …
