Entanglement of one-dimensional in Ising model with added dimerized Dzyaloshinskii-Morriya interaction

ABSTRACT:In this paper we focus the entanglement on 1D dimerized system antiferromagnetic (ferromagnetic) in Ising model with added nearest-neighbor interactions. we consider a system of 3-spin ½ particles in spin chain at low temperature with addeddimerized Dzyaloshinskii-Morriya(DM) interaction. Lack of inversion symmetry in the presence of the DM interaction stimulated us to study entanglement of the three-qubit through symmetric and non-symmetric ways for antiferromagnetic and ferromagnetic cases.and calculate the thermal entanglement (concurrence) of any two spins as a function of dimerized (DM) interaction and find some intriguing result.
