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…
