Fluctuations in Single-Shot $\epsilon$-Deterministic Work Extraction [PDF]

, 2017
There has been an increasing interest in the quantification of nearly deterministic work extraction from a finite number of copies of microscopic particles in finite time.

Posterior probability and fluctuation theorem in stochastic processes

, 2009
A generalization of fluctuation theorems in stochastic processes is proposed. The new theorem is written in terms of posterior probabilities, which are introduced via the Bayes theorem.

Constraints on stochastic heat probability prescribed by exchange fluctuation theorems

Results in Physics, 2020
The amount of heat transfer from one body to another during a finite time contact is a stochastic variable. The observed probability of heat can be prescribed by the exchange fluctuation theorem and its extensions; however, it should be stipulated in ...

Equilibrium fluctuation theorems compatible with anomalous response

, 2012
Previously, we have derived a generalization of the canonical fluctuation relation between heat capacity and energy fluctuations $C=\beta^{2}$, which is able to describe the existence of macrostates with negative heat capacities ...

Fluctuation theorems for stochastic dynamics

, 2007
Fluctuation theorems make use of time reversal to make predictions about entropy production in many-body systems far from thermal equilibrium. Here we review the wide variety of distinct, but interconnected, relations that have been derived and ...

The Fluctuation Theorem

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.

Fluctuation theorems without time-reversal symmetry

, 2014
Fluctuation theorems establish deep relations between observables away from thermal equilibrium. Until recently, the research on fluctuation theorems was focused on time-reversal-invariant systems.

Jarzynski's equality, fluctuation theorems, and variance reduction: Mathematical analysis and numerical algorithms [PDF]

, 2019
In this paper, we study Jarzynski's equality and fluctuation theorems for diffusion processes. While some of the results considered in the current work are known in the (mainly physics) literature, we review and generalize these nonequilibrium theorems ...

Using Nonequilibrium Fluctuation Theorems to Understand and Correct Errors in Equilibrium and Nonequilibrium Simulations of Discrete Langevin Dynamics

Physical Review X, 2013
Common algorithms for computationally simulating Langevin dynamics must discretize the stochastic differential equations of motion. These resulting finite-time-step integrators necessarily have several practical issues in common: Microscopic ...

Information Thermodynamics for Time Series of Signal-Response Models

Entropy, 2019
The entropy production in stochastic dynamical systems is linked to the structure of their causal representation in terms of Bayesian networks. Such a connection was formalized for bipartite (or multipartite) systems with an integral fluctuation theorem ...
