摘要：We investigate the behavior of geometric global quantum discord(GGQD) and concurrence(C) between halfspins of a mixed-three-spin(1/2,1,1/2) system with the Ising-XY model for which spins(1,1/2) have the Ising interaction and half-spins(1/2,1/2) have both XY and the Dzyaloshinskii-Moriya interactions together,under the decoherence action.A single-ion anisotropy property with coefficient ζ is assumed for the spin-integer.This system which includes an analytical Hamiltonian is considered at the front of an external homogeneous magnetic field B in thermal equilibrium.Finally,we compare GGQD and C and express some interesting phase flip reactions of the total quantum correlation and pairwise entanglement between spins(1/2,1/2).Generally,we conclude that the concurrence and GGQD have different behaviors under the phase Hip channel.
