Ensemble Dependence of the Transient Fluctuation Theorem

, 2000
The Fluctuation Theorem gives an analytical expression for the probability of observing second law violating dynamical fluctuations, in nonequilibrium systems. At equilibrium statistical mechanical fluctuations are known to be ensemble dependent. In this

Statistics of work and fluctuation theorems for microcanonical initial states

New Journal of Physics, 2013
Work performed on a system in a microcanonical state by changes in a control parameter is characterized in terms of its statistics. The transition probabilities between eigenstates of the system Hamiltonians at the beginning and the end of the parameter ...

Deformed Jarzynski Equality

Entropy, 2017
The well-known Jarzynski equality, often written in the form e − β Δ F = 〈 e − β W 〉 , provides a non-equilibrium means to measure the free energy difference Δ F of a system at the same inverse temperature β based on an ...

Introducing one-shot work into fluctuation relations

New Journal of Physics, 2015
Two approaches to small-scale and quantum thermodynamics are fluctuation relations and one-shot statistical mechanics. Fluctuation relations (such as Crooks’ theorem and Jarzynski's equality) relate nonequilibrium behaviors to equilibrium quantities such

Non-equilibrium Thermodynamics and Fluctuations

, 2003
In the last ten years, a number of ``Conventional Fluctuation Theorems'' have been derived for systems with deterministic or stochastic dynamics, in a transient or in a non-equilibrium stationary state.

Fluctuation theorems for continuously monitored quantum fluxes

, 2010
It is shown that quantum fluctuation theorems remain unaffected if measurements of any kind and number of observables are performed during the action of a force protocol.

Thermodynamics of trajectories and local fluctuation theorems for harmonic quantum networks

New Journal of Physics, 2015
We present a general method to undertake a thorough analysis of the thermodynamics of the quantum jump trajectories followed by an arbitrary quantum harmonic network undergoing linear and bilinear dynamics.

Unifying approach for fluctuation theorems from joint probability distributions

, 2010
Any decomposition of the total trajectory entropy production for Markovian systems has a joint probability distribution satisfying a generalized detailed fluctuation theorem, when all the contributing terms are odd with respect to time reversal.

Flaw in Crooks Fluctuation Theorem

Edelweiss Chemical Science Journal, 2018
The existence of Crooks fluctuation theorem (even at microscopic level, in a very short time period) is a direct threat to the second law of thermodynamics. In this paper, we will underline the flaw that exists in Crooks fluctuation theorem assumptions, and thus, we will confirm the validity of the second law of thermodynamics at any temperature, pressure,
