4 Thermal entanglement of spins in a nonuniform magnetic field

Abstract

We study the effect of nonuniformities in the magnetic field on the thermal entanglement of a two spin system. We show that in the ferromagnetic case a very small nonuniformity is capable to produce large values of thermal entanglement. In the antiferromagnetic case, nonuniformity only slightly raises the threshold temperature, but lowers the value of entanglement. email:asoudeh@mehr.sharif.edu Corresponding author, email:vahid@sharif.edu
