Entanglement entropy of disordered quantum chains following a global quench
Entanglement entropy of disordered quantum chains following a global quench
We numerically investigate the growth of the entanglement entropy ${S}_{\mathrm{ent}}(t)$ in time $t$, after a global quench from a product state, in quantum chains with various kinds of disorder. The main focus is, in particular, on fermionic chains with bond disorder. In the noninteracting case at criticality we numerically test …
