Work fluctuation theorems for harmonic oscillators [PDF]
, 2006 International audienceThe work fluctuations of an oscillator in contact with a thermostat and driven out of equilibrium by an external force are studied experimentally and theoretically within the context of Fluctuation Theorems (FTs).

Harnessing fluctuations in thermodynamic computing via time-reversal symmetries
Physical Review Research, 2021 We experimentally demonstrate that highly structured distributions of work emerge during even the simple task of erasing a single bit. These are signatures of a refined suite of time-reversal symmetries in distinct functional classes of microscopic ...

Relativistic fluctuation theorems [PDF]
Comptes Rendus. Physique, 2007 To reveal how nonequilibrium physics and relativity theory intertwine, this article studies relativistic Brownian motion under cosmic expansion. Two fluctuation theorems for the entropy Δ s , which is locally produced in this extreme nonequilibrium situation, are presented and proven.

The steady state fluctuation relation for the dissipation function [PDF]
, 2007 We give a proof of transient fluctuation relations for the entropy production (dissipation function) in nonequilibrium systems, which is valid for most time reversible dynamics. We then consider the conditions under which a transient fluctuation relation

Stochastic thermodynamics and fluctuation theorems for non-linear systems
New Journal of Physics, 2021 We extend stochastic thermodynamics by relaxing the two assumptions that the Markovian dynamics must be linear and that the equilibrium distribution must be a Boltzmann distribution.

Fluctuation-Dissipation Theorems for Multiphase Flow in Porous Media
Entropy, 2021 A thermodynamic description of porous media must handle the size- and shape-dependence of media properties, in particular on the nano-scale. Such dependencies are typically due to the presence of immiscible phases, contact areas and contact lines.

Fluctuation theorem and chaos [PDF]
The European Physical Journal B, 2008 The heat theorem (i.e. the second law of thermodynamics or the existence of entropy) is a manifestation of a general property of hamiltonian mechanics and of the ergodic Hypothesis. In nonequilibrium thermodynamics of stationary states the chaotic hypothesis plays a similar role: it allows a unique determination of the probability distribution (called {

Fluctuation Dissipation Theorem [PDF]
Physical Review, 1956 The fluctuation dissipation theorem (Nyquist formula) is shown to be exact and a number of generalizations of it are given, including a four-dimensional formulation which is useful in the quantum theory of fields. The more general theorem can be used to calculate vacuum expectation values of field operators, and to deduce covariant commutation ...
