Time-dependent fluctuation theorem [PDF]
Physical Review E, 2003 The fluctuation theorem (FT) is a generalization of the second law of thermodynamics that applies to small systems observed for short times. For thermostated systems it gives the probability ratio that entropy will be consumed rather than produced. In the present paper, we propose a version of the FT that applies to thermostated dissipative systems ...

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.

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.

Extension of the Fluctuation Theorem [PDF]
Physical 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 ...

Fluctuation theorems from Bayesian retrodiction [PDF]
Physical Review E, 2021 Quantitative studies of irreversibility in statistical mechanics often involve the consideration of a reverse process, whose definition has been the object of many discussions, in particular for quantum mechanical systems. Here we show that the reverse channel very naturally arises from Bayesian retrodiction, both in classical and quantum theories ...

Fluctuation theorem between non-equilibrium states in an RC circuit
New Journal of Physics, 2015 Fluctuation theorems impose constraints on the probability of observing negative entropy production in small systems driven out of equilibrium. The range of validity of fluctuation theorems has been extensively tested for transitions between equilibrium ...

Fluctuation Theorems for a Quantum Channel
Physical Review X, 2019 We establish the general framework of quantum fluctuation theorems by finding the symmetry between the forward and backward transitions of any given quantum channel.

Quasiprobability Distribution for Heat Fluctuations in the Quantum Regime
PRX Quantum, 2020 The standard approach to deriving fluctuation theorems fails to capture the effect of quantum correlation and coherence in the initial state of the system.
