Estimation of equilibration time scales from nested fraction approximations
Christian Bartsch, Anatoly Dymarsky, Mats H. Lamann +3
We consider an autocorrelation function of a quantum mechanical system through the lens of the so-called recursive method, by iteratively evaluating Lanczos coefficients, or solvin…
Characterization of random features of chaotic eigenfunctions in unperturbed basis
Jiaozi Wang, Wen-ge Wang
In this paper, we study random features manifested in components of energy eigenfunctions of quantum chaotic systems, given in the basis of unperturbed, integrable systems. Based o…
Interplay of decoherence and relaxation in a two-level system interacting with an infinite-temperature reservoir
Jiaozi Wang, Jochen Gemmer
We study the time evolution of a single qubit in contact with a bath, within the framework of projection operator methods. Employing the so-called modified Redfield theory which al…
Entanglement dynamics and classical complexity
Jiaozi Wang, Barbara Dietz, Dario Rosa +1
We study the dynamical generation of entanglement for a two-body interacting system, starting from a separable coherent state. We show analytically that in the quasiclassical regim…
Classicality, Markovianity and local detailed balance from pure state dynamics
Philipp Strasberg, Andreas Winter, Jochen Gemmer +1
When describing the effective dynamics of an observable in a many-body system, the repeated randomness assumption, which states that the system returns in a short time to a maximum…
Stability of Exponentially Damped Oscillations under Perturbations of the Mori-Chain
Robin Heveling, Jiaozi Wang, Christian Bartsch +1
There is an abundance of evidence that some relaxation dynamics, e.g., exponential decays, are much more common in nature than others. Recently, there have been attempts to trace t…
