Local entanglement and quantum phase transition in 1D transverse field Ising model
Shi-Quan Su, Jun-Liang Song, Shi-Jian Gu
In this paper, we study the entanglement between two-neighboring sites and the rest of the system in a simple quantum phase transition of 1D transverse field Ising model. We find t…
