Note on cond-mat/0510119: Jarzynski equation for adiabatically stretched rotor

TL;DR

This paper clarifies that the Jarzynski equation remains valid during adiabatic stretching of a three-dimensional rotor, countering previous claims of violation.

Contribution

It corrects prior misconceptions by demonstrating the Jarzynski equation holds for adiabatic stretching of a 3D rotor, reaffirming its applicability.

Findings

Jarzynski equation is valid for adiabatic rotor stretching

Previous claims of violation are incorrect

Theoretical analysis confirms the equation's robustness

Abstract

In a recent article (cond-mat/0510119) it has been argued that the Jarzynski equation is violated for adiabatic stretching processes of a three dimensional rotor system. Here we want to show that the reasoning is not correct. Rather, the Jarzynski equation is fulfilled for this adiabatically stretched rotor.
