Diffusion constants from the recursion method
Jiaozi Wang, Mats H. Lamann, Robin Steinigeweg +1
Understanding the transport behavior of quantum many-body systems constitutes an important physical endeavor, both experimentally and theoretically. While a reliable classification…

Emergence of unitary symmetry of microcanonically truncated operators in chaotic quantum systems
Jiaozi Wang, Jonas Richter, Mats H. Lamann +3
We study statistical properties of matrix elements of observables written in the energy eigenbasis and truncated to small microcanonical windows. We present numerical evidence indi…

Lindblad dynamics from spatio-temporal correlation functions in nonintegrable spin-1/2 chains with different boundary conditions
Markus Kraft, Jonas Richter, Fengping Jin +6
We investigate the Lindblad equation in the context of boundary-driven magnetization transport in spin- chains. Our central question is whether the nonequilibrium steady state…
