Two-spin entanglement distribution near factorized states
Fabrizio Baroni, Andrea Fubini, Valerio Tognetti +1
We study the two-spin entanglement distribution along the infinite chain described by the XY model in a transverse field; closed analytical expressions are derived for the…
Entanglement and factorized ground states in two-dimensional quantum antiferromagnets
Tommaso Roscilde, Paola Verrucchi, Andrea Fubini +2
Making use of exact results and quantum Monte Carlo data for the entanglement of formation, we show that the ground state of anisotropic two-dimensional S=1/2 antiferromagnets in a…
Entanglement in quantum critical spin systems
Tommaso Roscilde, Paola Verrucchi, Andrea Fubini +2
We study the field dependence of the entanglement of formation in anisotropic S=1/2 antiferromagnetic chains and two-leg ladders displaying a T=0 field-driven quantum phase transit…
