Concurrence in the two dimensional XXZ- and transverse field Ising-models
arXiv:quant-ph/0312101 · doi:10.1016/j.physleta.2003.12.018
Abstract
Numerical results for the concurrence and bounds on the localizable entanglement are obtained for the square lattice spin-1/2 XXZ-model and the transverse field Ising-model at low temperatures using quantum Monte Carlo.
