The instantaneous fluctuation theorem [PDF]

open access: yesThe 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

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 ...

The Fluctuation Theorem

open access: yesAdvances 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: Work is not an observable [PDF]

open access: yesPhysical Review E, 2007
The characteristic function of the work performed by an external time-dependent force on a Hamiltonian quantum system is identified with the time-ordered correlation function of the exponentiated system's Hamiltonian. A similar expression is obtained for the averaged exponential work which is related to the free energy difference of equilibrium systems

Relativistic fluctuation theorems [PDF]

open access: yesComptes 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.

Fluctuation-dissipation theorem for non-equilibrium quantum systems [PDF]

open access: yesQuantum, 2018
The fluctuation-dissipation theorem (FDT) is a central result in statistical physics, both for classical and quantum systems. It establishes a relationship between the linear response of a system under a time-dependent perturbation and time correlations ...
