Quasi-classical descendants of disordered vertex models with boundaries
Antonio Di Lorenzo, Luigi Amico, Kazuhiro Hikami +2
We study descendants of inhomogeneous vertex models with boundary reflections when the spin-spin scattering is assumed to be quasi--classical. This corresponds to consider certain…

Scaling of Entanglement close to a Quantum Phase Transitions
A. Osterloh, L. Amico, G. Falci +1
In this Letter we discuss the entanglement near a quantum phase transition by analyzing the properties of the concurrence for a class of exactly solvable models in one dimension. W…
