Description:
Author(s): M. Usman, Asif Ilyas, and Khalid Khan We investigate entanglement and quantum phase transition in a two-dimensional Heisenberg anisotropic spin- 1 / 2 XY model, using the quantum renormalization-group method (QRG) on a square lattice of N × N sites. The entanglement through geometric average of concurrences is calculated after each step of th… [Phys. Rev. A 92, 032327] Published Mon Sep 28, 2015
