Absence of thermalization after a local quench and strong violation of the eigenstate thermalization hypothesis
Peter Reimann, Christian Eidecker-Dunkel
Absence of thermalization after a global quantum quench is a well-established numerical observation in integrable many-body systems, and can be empirically related to a violation o…
Basis dependence of eigenstate thermalization
Lennart Dabelow, Christian Eidecker-Dunkel, Peter Reimann
Eigenstate thermalization refers to the property that an energy eigenstate of a many-body system is indistinguishable from a thermal equilibrium ensemble at the same energy as far…
Thermalization in a simple spin-chain model
Peter Reimann, Christian Eidecker-Dunkel
We consider the common spin-1/2 XX-model in one dimension with open boundary conditions and a large but finite number of spins. The system is in thermal equilibrium at times t<0, a…
Random-matrix approach to time-dependent forcing in many-body quantum systems
Lennart Dabelow, Peter Reimann
Changing some of its parameters over time is a paradigmatic way of driving an otherwise isolated many-body quantum system out of equilibrium, and a vital ingredient for building qu…
Onsager's regression hypothesis adjusted to quantum systems
Peter Reimann, Christian Eidecker-Dunkel
Onsager's regression hypothesis connects the temporal relaxation of close-to-equilibrium systems with their dynamical correlation functions at thermal equilibrium. While the hypoth…
Stalled response near thermal equilibrium in periodically driven systems
Lennart Dabelow, Peter Reimann
The question of how systems respond to perturbations is ubiquitous in physics. Predicting this response for large classes of systems becomes particularly challenging if many degree…
Non-equilibration, synchronization, and time crystals in isotropic Heisenberg models
P. Reimann, P. Vorndamme, J. Schnack
Isotropic but otherwise largely arbitrary Heisenberg models in the presence of a homogeneous magnetic field are considered, including various integrable, non-integrable, as well as…
