Macroscopically deterministic, Markovian thermalization in finite quantum spin systems
Hendrik Niemeyer, Kristel Michielsen, Hans de Raedt +1
A key feature of non-equilibrium thermodynamics is the Markovian, deterministic relaxation of coarse observables such as, for example, the temperature difference between two macros…
Pushing the limits of the eigenstate thermalization hypothesis towards mesoscopic quantum systems
Robin Steinigeweg, Abdelah Khodja, Hendrik Niemeyer +2
In the ongoing discussion on thermalization in closed quantum many-body systems, the eigenstate thermalization hypothesis (ETH) has recently been proposed as a universal concept wh…
Transport in topologically disordered one-particle, tight-binding models
A. Khodja, H. Niemeyer, J. Gemmer
We aim at quantitatively determining transport parameters like conductivity, mean free path, etc., for simple models of spatially completely disordered quantum systems, comparable…
Onset of Fokker-Planck dynamics within a Closed Finite Spin System
Hendrik Niemeyer, Daniel Schmidke, Jochen Gemmer
Relaxation according to Fokker-Planck equations is a standard scenario in classical statistical mechanics. It is however not obvious how such an equilibration may emerge within a c…
Transport in the 3-dimensional Anderson model: an analysis of the dynamics on scales below the localization length
Robin Steinigeweg, Hendrik Niemeyer, Jochen Gemmer
Single-particle transport in disordered potentials is investigated on scales below the localization length. The dynamics on those scales is concretely analyzed for the 3-dimensiona…
