Time reversal symmetry breaking and odd viscosity in active fluids: Green-Kubo and NEMD results

24 Feb 2020 Hargus Cory Klymko Katherine Epstein Jeffrey M. Mandadapu Kranthi K.

Active fluids, which are driven at the microscale by non-conservative forces, are known to exhibit novel transport phenomena due to the breaking of time reversal symmetry. Recently, Epstein and Mandadapu [arXiv:1907.10041 (2019)] obtained Green-Kubo relations for the full set of viscous coefficients governing isotropic chiral active fluids, including the so-called odd viscosity, invoking Onsager's regression hypothesis for decay of fluctuations in active non-equilibrium steady states...
