Abstract
Studying quantum correlation dynamics of a central two-qubit system coupled to Ising chain model, we obtain that the evolution of quantum discord and geometric measure of quantum discord for the central atoms. We find that quantum correlation exists a sudden transition in the weak coupled interaction near the quantum critical point of Ising chain. Moreover, the evolution of geometric measure of quantum discord in invariant to some extent.
