Thermal quantum discord of one-dimensional in three-qubit spin chain with nearest-neighbor and next-nearest neighbor and Dzyaloshinskii- Morriya interaction
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 4, Issue 11
Abstract
We have studied thermal quantum discord in three-qubit Ising model with nearestneighbor and next-nearest neighbor and Dzyaloshinskii-Moriya(DM) interaction. Lack of inversion symmetry in the presence of the DM interaction stimulated us to study quantum correlations of the three-qubit through symmetric (SY) and non-symmetric (NYS) ways for both ferromagnetic (FM) and antiferromagnetic (AF)Cases. We found that the discord with increasing the temperature T , at first the quantum correlations in the system increase, smoothlyreach the maximum, and then turn again into zero .
