Characterizing the Non-equilibrium Dynamics of Field-Driven Correlated Quantum Systems

open access: yesFrontiers in Physics, 2020
Recent experimental advances in ultrafast phenomena have triggered renewed interest in the dynamics of correlated quantum systems away from equilibrium.

Finite bath fluctuation theorem [PDF]

open access: yesPhysical Review E, 2009
We demonstrate that a Finite Bath Fluctuation Theorem of the Crooks type holds for systems that have been thermalized via weakly coupling it to a bath with energy independent finite specific heat. We show that this theorem reduces to the known canonical and microcanonical fluctuation theorems in the two respective limiting cases of infinite and ...

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 [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 ...

The Kawasaki identity and the Fluctuation Theorem [PDF]

open access: yesThe 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.
