Entanglement in One-Dimensional Spin Systems
A. Osterloh, L. Amico, F. Plastina +1
For the anisotropic XY model in transverse magnetic field, we analyze the ground state and its concurrence-free point for generic anisotropy, and the time evolution of initial Bell…

Divergence of the entanglement range in low dimensional quantum systems
L. Amico, F. Baroni, A. Fubini +3
We study the pairwise entanglement close to separable ground states of a class of one dimensional quantum spin models. At T=0 we find that such ground states separate regions, in t…
