Scaling of free cumulants in closed system-bath setups
Merlin Füllgraf, Jochen Gemmer, Jiaozi Wang
The Eigenstate Thermalization Hypothesis (ETH) has been established as a cornerstone for understanding thermalization in quantum many-body systems. Recently, there has been growing…
Boundary-driven magnetization transport in the spin- XXZ chain: Role of the system-bath coupling strength and timescales
Mariel Kempa, Markus Kraft, Sourav Nandy +4
Understanding the transport properties of quantum many-body systems is a central challenge in condensed matter and statistical physics. Theoretical studies usually rely on two main…
Eigenstate Thermalization Hypothesis and Random Matrix Theory Universality in Few-Body Systems
Jiaozi Wang, Hua Yan, Robin Steinigeweg +1
In this paper, we study the Feingold-Peres model as an example, which is a well-known paradigm of quantum chaos. Using semiclassical analysis and numerical simulations, we study th…
Lanczos-Pascal approach to correlation functions in chaotic quantum systems
Merlin Füllgraf, Jiaozi Wang, Robin Steinigeweg +1
We suggest a method to compute approximations to temporal correlation functions of few-body observables in chaotic many-body systems in the thermodynamic limit based on the respect…
Scrutinizing the Mori memory function for diffusion in periodic quantum systems
Scott D. Linz, Jiaozi Wang, Robin Steinigeweg +1
Diffusion is an ubiquitous phenomenon. It is a widespread belief that as long as the area under a current autocorrelation function converges in time, the corresponding spatiotempor…
