Hydrodynamics and the fluctuation theorem [PDF]

open access: yesPhysical Review Letters, 2011
The fluctuation theorem is a pivotal result of statistical physics. It quantifies the probability of observing fluctuations which are in violation of the second law of thermodynamics.

Fluctuation Dissipation Theorem [PDF]

open access: yesPhysical 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 ...

Fluctuation Theorems [PDF]

open access: yesAnnual Review of Physical Chemistry, 2008
Fluctuation theorems, developed over the past 15 years, have resulted in fundamental breakthroughs in our understanding of how irreversibility emerges from reversible dynamics and have provided new statistical mechanical relationships for free-energy changes.

Quantum fluctuation theorem for dissipative processes

open access: yesPhysical Review Research, 2022
We present a general quantum fluctuation theorem for the entropy production of an open quantum system coupled to multiple environments, not necessarily at equilibrium.

Microcanonical quantum fluctuation theorems [PDF]

open access: yesPhysical Review E, 2008
Previously derived expressions for the characteristic function of work performed on a quantum system by a classical external force are generalized to arbitrary initial states of the considered system and to Hamiltonians with degenerate spectra. In the particular case of microcanonical initial states explicit expressions for the characteristic function ...

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
