According to the eigenstate thermalization ansatz, matrices representing generic few body observables take on a specific form when displayed in the eigenbasis of a chaotic Hamiltonian. We examine the effect of environmental induced decoherence on the dynamics of observables that conform with said eigenstate thermalization ansatz. The obtained result refers to a description of the dynamics in terms of an integro-differential equation of motion of the Nakajima-Zwanzig form. We find that…

Abstract Evidently, some relaxation dynamics, e.g. exponential decays, are much more common in nature than others. Recently there have been attempts to explain this observation on the basis of…

If the off-diagonal part of the ETH applies, then the relaxation process can become independent of whether or not a state is close to equilibrium, and the dynamics is generated by a single correlation function in the context of LRT.

Thermalization and its mechanism for generic isolated quantum systems

- PhysicsNature

It is demonstrated that a generic isolated quantum many-body system does relax to a state well described by the standard statistical-mechanical prescription, and it is shown that time evolution itself plays a merely auxiliary role in relaxation, and that thermalization instead happens at the level of individual eigenstates, as first proposed by Deutsch and Srednicki.

The existence of a critical value of the interaction, depending on the mean level spacing of the environment, is shown, above which the dynamics is self-averaging and closely obey a master equation for the time evolution of the observables of the two-level system.
