Özet:

 

The bounds of entanglement on antiferromagnetic (AF) isotropic Heisenberg spin-1/2 chain including dipole-  dipole interaction (D) were investigated. The Quantum Monte Carlo method based on loop algorithm was employed to  calculate the two-spin and single-spin expectation values mediating the lower and upper bounds. It was revealed that  D and Bz (the applied magnetic field) were pivotal parameters in controlling either entanglement creation/extinction or  entanglement enhancement/weakening. Rival regions indicated a revival phenomenon depending on the temperature for  various strengths of D which also showed a nonmonotonic behavior under certain Bz identifying critical points. Even if  thermal agitations break the stability of strong D entanglement, it remains invariable at very low temperatures.
