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…
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…
Allosteric impurity effects in long spin chains
Christian Eidecker-Dunkel, Peter Reimann
Allosterism traditionally refers to local changes in an extended object, for instance the binding of a ligand to a macromolecule, leading to a localized response at some other, pos…
