Analytic solution of the domain-wall nonequilibrium stationary state
We consider the out-of-equilibrium dynamics generated by joining two domains with
arbitrary opposite magnetizations. We study the stationary state which emerges by the …

Transport in out-of-equilibrium XXZ chains: Nonballistic behavior and correlation functions
We consider the nonequilibrium protocol where two semi-infinite gapped XXZ chains,
initially prepared in different equilibrium states, are suddenly joined together. At large times …

Random state technology
We review and extend, in a self-contained way, the mathematical foundations of numerical
simulation methods that are based on the use of random states. The power and versatility of …

Weak integrability breaking: Chaos with integrability signature in coherent diffusion
M Žnidarič - Physical Review Letters, 2020 - APS
We study how perturbations affect dynamics of integrable many-body quantum systems,
causing transition from integrability to chaos. Looking at spin transport in the Heisenberg …

Selected applications of typicality to real-time dynamics of quantum many-body systems
T Heitmann, J Richter, D Schubert… - … für Naturforschung A, 2020 - degruyter.com
Loosely speaking, the concept of quantum typicality refers to the fact that a single pure state
can imitate the full statistical ensemble. This fact has given rise to a rather simple but …
