Fluctuation theorem on a Riemannian manifold
Physical Review ResearchBased 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 ...

The instantaneous fluctuation theorem [PDF]
The 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]
The 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.

Fluctuation theorems for autonomous work. [PDF]
Proc Natl Acad Sci U S AClassical fluctuation theorems for work have been obtained theoretically, and verified experimentally, within a nonautonomous framework in which work is performed on a system of interest, S , by the ...

Finite bath fluctuation theorem [PDF]
Physical 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 ...

The Kawasaki identity and the Fluctuation Theorem [PDF]
The Journal of Chemical Physics, 2004 In this paper we show that the Fluctuation Theorem of Evans and Searles [D. J. Evans, D. J. Searles, Phys. Rev. E 50, 1645 (1994)] implies that the Kawasaki function 〈exp(−Ωt)〉 is unity for all time t. We confirm this relationship using experimental data obtained using optical tweezers, and show that the Kawasaki function is a valuable diagnostic tool.

Advances in Physics, 2002 The question of how reversible microscopic equations of motion can lead to irreversible macroscopic behaviour has been one of the central issues in statistical mechanics for more than a century. The basic issues were known to Gibbs. Boltzmann conducted a very public debate with Loschmidt and others without a satisfactory resolution.

Experimental Validation of Fully Quantum Fluctuation Theorems Using Dynamic Bayesian Networks [PDF]
, 2021 Fluctuation theorems are fundamental extensions of the second law of thermodynamics for small systems. Their general validity arbitrarily far from equilibrium makes them invaluable in nonequilibrium physics.

Stochastic Thermodynamics of a Finite Quantum System Coupled to Two Heat Baths
Entropy, 2023 We consider a situation where an N-level system (NLS) is coupled successively to two heat baths with different temperatures without being necessarily thermalized and approaches a steady state. For this situation we apply a general Jarzynski-type equation
