Pairwise Entanglement and Quantum Phase Transitions in Spin Systems
-
Abstract
We examine several well-known quantum spin models and categorize
the behaviour of pairwise entanglement at quantum phase transitions. A
unified picture on the connection between the entanglement and quantum
phase transition in spin systems is presented.
