Contribution

It introduces a derivation of the Fluctuation Theorem for a tilted ratchet system, extending its applicability to biological physics contexts.

Findings

FT holds for the steady state of the tilted ratchet system

Derived under natural assumptions, the FT relates entropy production symmetry

Potential implications for biological systems modeled by ratchets

Abstract

Fluctuation Theorem(FT) has been studied as far from equilibrium theorem, which relates the symmetry of entropy production. To investigate the application of this theorem, especially to biological physics, we consider the FT for tilted rachet system. Under, natural assumption, FT for steady state is derived.
