Entanglement across extended random defects in the XX spin chain
Róbert Juhász
We study the half-chain entanglement entropy in the ground state of the spin-1/2 XX chain across an extended random defect, where the strength of disorder decays with the distance…

Entanglement between random and clean quantum spin chains
Robert Juhász, István A. Kovács, Gergő Roósz +1
The entanglement entropy in clean, as well as in random quantum spin chains has a logarithmic size-dependence at the critical point. Here, we study the entanglement of composite sy…
