Comment on "Nonequilibrium Equality for Free Energy Differences"

Authors: Gokaran Shukla

The existence of Jarzynski “equality” is a direct threat to the second law of thermodynamics. Jarzynski [Phys. Rev. Lett. 78, 2690 (1997)] uses Liouville equation of motion in dissipative system and derives a relation between ir-reversible work and change in Helmholtz free energy. In this comment, we will underline the flaw that exists in Jarzynski analysis, and thus, we will show that exact relation between ir-reversible works and change in Helmholtz/Gibbs free energy is impossible in any real thermodynamical system.
