# Transport in out-of-equilibrium XXZ chains: Nonballistic behavior and correlation functions

@article{Piroli2017TransportIO, title={Transport in out-of-equilibrium XXZ chains: Nonballistic behavior and correlation functions}, author={Lorenzo Piroli and Jacopo de Nardis and Mario Collura and Bruno Bertini and Maurizio Fagotti}, journal={Physical Review B}, year={2017}, volume={96}, pages={115124} }

We consider the nonequilibrium protocol where two semi-infinite gapped XXZ chains, initially prepared in different equilibrium states, are suddenly joint together. At large times, a generalized hydrodynamic description applies, according to which the system can locally be represented by space- and time- dependent stationary states. The magnetization displays an unusual behavior: depending on the initial state, its profile may exhibit abrupt jumps that can not be predicted directly from the…
