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.

Quantum fluctuation theorem for dissipative processes

open access: yesPhysical Review Research, 2022
We present a general quantum fluctuation theorem for the entropy production of an open quantum system coupled to multiple environments, not necessarily at equilibrium.

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.

The instantaneous fluctuation theorem [PDF]

open access: yesThe Journal of Chemical Physics, 2013
We give a derivation of a new instantaneous fluctuation relation for an arbitrary phase function which is odd under time reversal. The form of this new relation is not obvious, and involves observing the system along its transient phase space trajectory both before and after the point in time at which the fluctuations are being compared. We demonstrate

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.
