Fluctuation Theorem of Information Exchange within an Ensemble of Paths Conditioned on Correlated-Microstates [PDF]
Entropy, 2019 Fluctuation theorems are a class of equalities that express universal properties of the probability distribution of a fluctuating path functional such as heat, work or entropy production over an ensemble of trajectories during a non-equilibrium process ...

The instantaneous fluctuation theorem [PDF]
The 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

Isobaric–isothermal fluctuation theorem [PDF]
The Journal of Chemical Physics, 2002 The fluctuation theorem (FT) gives an analytical expression for the probability that in a finite nonequilibrium system observed for a finite time, the Second Law of Thermodynamics is violated. Since FT deals with fluctuations, the precise form of the theorem is dependent on the particular statistical mechanical ensemble.

Information in Biological Systems and the Fluctuation Theorem [PDF]
Entropy, 2014 Some critical trends in information theory, its role in living systems and utilization in fluctuation theory are discussed. The mutual information of thermodynamic coupling is incorporated into the generalized fluctuation theorem by using information ...

Quasiprobability fluctuation theorem behind the spread of quantum information [PDF]
Communications PhysicsInformation spreads in time. For example, correlations dissipate when the correlated system locally couples to a third party, such as the environment. This simple but important fact forms the known quantum data-processing inequality.

The Kawasaki identity and the Fluctuation Theorem [PDF]
The Journal of Chemical Physics, 2004 In this paper we show that the Fluctuation Theorem of Evans and Searles [D. J. Evans, D. J. Searles, Phys. Rev. E 50, 1645 (1994)] implies that the Kawasaki function 〈exp(−Ωt)〉 is unity for all time t. We confirm this relationship using experimental data obtained using optical tweezers, and show that the Kawasaki function is a valuable diagnostic tool.

The Fluctuation Theorem and Dissipation Theorem for Poiseuille Flow [PDF]
Journal of Physics: Conference Series, 2011 The fluctuation theorem and the dissipation theorem provide relationships to describe nonequilibrium systems arbitrarily far from, or close to equilibrium. They both rely on definition of a central property, the dissipation function. In this manuscript we apply these theorems to examine a boundary thermostatted system undergoing Poiseuille flow.

Trajectory Class Fluctuation Theorem [PDF]
Journal of Statistical PhysicsAbstract The Trajectory Class Fluctuation Theorem (TCFT) presents equalities between thermodynamic quantities, such as work costs and free energy changes, and the probabilities of classes of system-state trajectories in equilibrium-steady-state nonequilibrium processes.

Ensembles, turbulence and fluctuation theorem [PDF]
The European Physical Journal E, 2020 The fluctuation theorem is considered intrinsically linked to reversibility and therefore its phenomenological consequence, the fluctuation relation, is sometimes considered not applicable. Nevertheless here is considered the paradigmatic example of irreversible evolution, the 2D Navier-Stokes incompressible flow, to show how universal properties of ...

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.
