Title:	Analytical study of thermal entanglement in a two-dimensional J1-J2 model
Authors:	Eryigit, Recep Gündüç, Yiğit Eryigit, Resul
Abstract:	We have investigated the ground-state and the thermal entanglement properties of a two-dimensional frustrated spin 1/2 cluster by calculating the pairwise concurrence and negativity. It is found that an increase in temperature can lead to an enhancement of pairwise entanglement for a certain range of the frustration parameter. We have, also, found that negativity is equal to the half of the concurrence for the model considered here. © 2006 Elsevier B.V. All rights reserved.
