Entanglement witnesses in the XY chain: Thermal equilibrium and postquench nonequilibrium states
Ferenc Iglói, Géza Tóth
We use entanglement witnesses to detect entanglement in the XY chain in thermal equilibrium and determine the temperature bound below which the state is detected as entangled. We c…

Random-bond antiferromagnetic Ising model in a field
Jean-Christian Anglès d'Auriac, Ferenc Iglói
Using combinatorial optimisation techniques we study the critical properties of the two- and the three-dimensional Ising model with uniformly distributed random antiferromagnetic c…
