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.Physics, MultidisciplinarySCI(E)中国科技核心期刊(ISTIC)0ARTICLE102737-27402
