Contribution
It introduces a new representation of the steady-state distribution function applicable to sheared granular systems without microscopic time-reversal symmetry.
Findings
Derived a new representation for nonequilibrium steady states
Applicable to sheared granular systems with broken symmetry
Connects excess free energy production to distribution function
Abstract
We derive the representation of the nonequilibrium steady-state distribution function which is expressed in terms of the excess free energy production. This representation resembles the one derived recently by Komatsu and Nakagawa [Phys. Rev. Lett. 100 (2008), 030601] resting on the use of microscopic time-reversal symmetry, but our representation applies also to sheared granular systems in which such a symmetry is broken.
