Nonequilibrium steady-state Kubo formula: Equality of transport coefficients
Nonequilibrium steady-state Kubo formula: Equality of transport coefficients
We address the question of whether transport coefficients obtained from a unitary closed system setting, i.e., the standard equilibrium Green-Kubo formula, are the same as the ones obtained from a weakly driven nonequilibrium steady-state calculation. We first derive a nonequilibrium Kubo-like expression for the steady-state diffusion constant expressed as a …
