Fluctuation theorem on a Riemannian manifold

open access: yesPhysical Review Research
Based on the covariant underdamped and overdamped Langevin equations with Stratonovich coupling to multiplicative noises and the associated Fokker-Planck equations on a Riemannian manifold, we present the first law of stochastic thermodynamics on the ...

Detailed Fluctuation Theorems: A Unifying Perspective

open access: yesEntropy, 2018
We present a general method to identify an arbitrary number of fluctuating quantities which satisfy a detailed fluctuation theorem for all times within the framework of time-inhomogeneous Markovian jump processes.

By-passing fluctuation theorems [PDF]

open access: yesQuantum, 2020
Fluctuation theorems impose constraints on possible work extraction probabilities in thermodynamical processes. These constraints are stronger than the usual second law, which is concerned only with average values. Here, we show that such constraints, expressed in the form of the Jarzysnki equality, can be by-passed if one allows for the use of ...

Fluctuation Theorems [PDF]

open access: yesAnnual Review of Physical Chemistry, 2008
Fluctuation theorems, developed over the past 15 years, have resulted in fundamental breakthroughs in our understanding of how irreversibility emerges from reversible dynamics and have provided new statistical mechanical relationships for free-energy changes.

Extension of the Fluctuation Theorem [PDF]

open access: yesPhysical Review Letters, 2003
Heat fluctuations are studied in a dissipative system with both mechanical and stochastic components for a simple model: a Brownian particle dragged through water by a moving potential. An extended stationary state fluctuation theorem is derived. For infinite time, this reduces to the conventional fluctuation theorem only for small fluctuations; for ...

White-noise fluctuation theorem for Langevin dynamics

open access: yesNew Journal of Physics, 2022
Fluctuation theorems (FTs) based on time-reversal have provided remarkable insight into the non-equilibrium statistics of thermodynamic quantities like heat, work, and entropy production.

A local fluctuation theorem [PDF]

open access: yesThe Journal of Chemical Physics, 2001
The fluctuation theorem gives an analytic expression for the probability, in a nonequilibrium system of finite size observed for a finite time, that the dissipative flux will flow in the reverse direction to that required by the second law of thermodynamics. In the present paper a local version of the fluctuation theorem (LFT) is derived heuristically.

Characterizing the Non-equilibrium Dynamics of Field-Driven Correlated Quantum Systems

open access: yesFrontiers in Physics, 2020
Recent experimental advances in ultrafast phenomena have triggered renewed interest in the dynamics of correlated quantum systems away from equilibrium.

Finite bath fluctuation theorem [PDF]

open access: yesPhysical Review E, 2009
We demonstrate that a Finite Bath Fluctuation Theorem of the Crooks type holds for systems that have been thermalized via weakly coupling it to a bath with energy independent finite specific heat. We show that this theorem reduces to the known canonical and microcanonical fluctuation theorems in the two respective limiting cases of infinite and ...
