Comment on "Nonequilibrium thermodynamics with binary quantum correlations"

Abstract

The article [Phys. Rev.

E 96, 032106 (2017)] recovers conservation laws and derives the H-theorem for the kinetic equation with gradient corrections. Here we show that this approach is not valid, leading to missing terms in the balance of energy and momentum and to disagreement with correlation entropy known from the Enskog equation.
