Entanglement entropy in quantum spin chains with broken reflection symmetry
Zoltan Kadar, Zoltan Zimboras
We investigate the entanglement entropy of a block of L sites in quasifree translation-invariant spin chains concentrating on the effect of reflection symmetry breaking. The majora…

Entanglement distillation from quasifree Fermions
Zoltan Kadar, Michael Keyl, Dirk Schlingemann
We develop a scheme to distill entanglement from bipartite Fermionic systems in an arbitrary quasifree state. It can be applied if either one system containing infinite one-copy en…
