Quantum entanglement and quantum phase transition in the XY model with staggered Dzyaloshinskii-Moriya interaction

We study the quantum entanglement and quantum phase transition (QPT) of the anisotropic spin-1/2 XY model with staggered Dzyaloshinskii-Moriya (DM) interaction by means of the quantum renormalization group method. The scaling of coupling constants and the critical points of the system are obtained....
