Entanglement fluctuation theorems [PDF]

Physical Review A, 2019
Pure state entanglement transformations have been thought of as irreversible, with reversible transformations generally only possible in the limit of many copies. Here, we show that reversible entanglement transformations do not require processing on the many copy level, but can instead be undertaken on individual systems, provided the amount of ...

Superstatistical generalization of the work fluctuation theorem

, 2003
We derive a generalized version of the work fluctuation theorem for nonequilibrium systems with spatio-temporal temperature fluctuations. For chi-square distributed inverse temperature we obtain a generalized fluctuation theorem based on q-exponentials ...

The Fluctuation Theorem and Its Practical Limitations: A Numerical Example

Dynamics
The Fluctuation Theorem establishes a relationship between microscopic reversibility and macroscopic irreversible phenomena, such as dissipation. In this short paper, we present an elementary derivation of this theorem within the framework of stochastic ...

Focus on nonequilibrium fluctuation relations: from classical to quantum

New Journal of Physics, 2015
The fluctuation dissipation theorem is at the heart of equilibrium statistical mechanics. For a system away from thermal equilibrium, generalized nonequilibrium fluctuation relations have been found in recent years.

Fluctuation Theorems for Heat Exchanges between Passive and Active Baths

Entropy
In addition to providing general constraints on probability distributions, fluctuation theorems allow us to infer essential information on the role played by temperature in heat exchange phenomena.

On fluctuating momentum exchange in idealised models of air–sea interaction [PDF]

Nonlinear Processes in Geophysics, 2019
The dynamics of three local models, for momentum transfer at the air–sea interface, is compared. The models differ by whether or not the ocean velocity is included in the shear calculation applied to the ocean and the atmosphere.

Can quantum regression theorem be reconciled with quantum fluctuation dissipation theorem ?

, 2002
In the attempt to derive the regression theorem from the fluctuation dissipation theorem several authors claim the violation of the former theorem in the quantum case.

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

Nonlinear Non-Equilibrium Thermodynamics Based on the Ehrenfest–Klein Model

Entropy, 2020
Nonlinear non-equilibrium thermodynamic relations have been constructed based on the generalized Ehrenfest−Klein model. Using these relations, the behavior of the entropy and its production in time at arbitrary deviations from equilibrium has been ...

Generalisation of fluctuation-dissipation theorem to systems with absorbing states

New Journal of Physics, 2023
Systems that evolve towards a state from which they cannot depart are common in nature. But the fluctuation-dissipation theorem (FDT), a fundamental result in statistical mechanics, is mainly restricted to systems near-stationarity.
