Testing the Steady-State Fluctuation Relation in the Solar Photospheric Convection

open access: yesEntropy, 2020
The turbulent thermal convection on the Sun is an example of an irreversible non-equilibrium phenomenon in a quasi-steady state characterized by a continuous entropy production rate.

Spatial fluctuation theorem [PDF]

open access: yes, 2015
For non-equilibrium systems of interacting particles and for interacting diffusions in d-dimensions, a novel fluctuation relation is derived. The theorem establishes a quantitative relation between the probabilities of observing two current values in ...

Fluctuation Dissipation Theorem and Dynamical renormalization Group [PDF]

open access: yes, 1996
The relation between a recently introduced dynamical real-space renormalization group and the fluctuation-dissipation theorem is discussed.

Fluctuation theorem in rachet system [PDF]

open access: yesJournal of Physics A: Mathematical and General, 2004
Fluctuation Theorem(FT) has been studied as far from equilibrium theorem, which relates the symmetry of entropy production. To investigate the application of this theorem, especially to biological physics, we consider the FT for tilted rachet system. Under, natural assumption, FT for steady state is derived.

Linear Landau damping, Schrödinger equation, and fluctuation theorem [PDF]

open access: yes
ORCID 0000-0001-5444-1758A linearized Vlasov–Poisson system of equations is transformed into a Schrödinger equation, which is used to demonstrate that the fluctuation theorem holds for the relative stochastic entropy, defined in terms of the probability ...

Design principles for enhancing phase sensitivity and suppressing phase fluctuations simultaneously in biochemical oscillatory systems

open access: yesNature Communications, 2018
Biochemical processes require both high sensitivity and low fluctuation which is incompatible with the fluctuation dissipation theorem. Here Fei et al. model biochemical oscillators to show how free energy dissipation leads to both a suppression of phase

Tensor-network approaches to counting statistics for the current in a boundary-driven diffusive system

open access: yesNew Journal of Physics, 2022
We apply tensor networks to counting statistics for the stochastic particle transport in an out-of-equilibrium diffusive system. This system is composed of a one-dimensional channel in contact with two particle reservoirs at the ends.

Fluctuation theorem between non-equilibrium states in an RC circuit

open access: yesNew 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 ...

Entropy production of a closed Hamiltonian system via the detailed fluctuation relation

open access: yesPhysical Review Research, 2021
We revisit the problem of emergent irreversibility in a closed Hamiltonian system in light of the detailed fluctuation relation by invoking an imperfect Loschmidt demon that performs a time-reversal operation with a finite precision.
