Entanglement entropy of disordered quantum chains following a global quench
Y. Zhao, F. Andraschko, J. Sirker
We numerically investigate the growth of the entanglement entropy S_{ent}(t) in time t---after a global quench from a product state---in quantum chains with various kinds of disord…

Propagation of a single hole defect in the one-dimensional Bose-Hubbard model
F. Andraschko, J. Sirker
We study nonequilibrium dynamics in the one-dimensional Bose-Hubbard model starting from an initial product state with one boson per site and a single hole defect. We find that for…

Dynamical quantum phase transitions and the Loschmidt echo: A transfer matrix approach
F. Andraschko, J. Sirker
A boundary transfer matrix formulation allows to calculate the Loschmidt echo for one-dimensional quantum systems in the thermodynamic limit. We show that non-analyticities in the…
