Super Quantum Discord Behaviors in Two-Qubit Heisenberg XYZ Model with Intrinsic Decoherence

In this paper, dynamics of super-quantum discord in Heisenberg model that has Dzyaloshinskii-Moriya interaction, we will study the influence of environmental decoherence by taking Lyndblad equation. We consider Werner state as the initial state of the system. By calculating the time evolution of the system, we figure out the influence of mixture degree r on the dynamics such as super quantum discord, quantum discord and cancurrence. A remarkable result is that when the initial state is Bell state the concurrence decays from 1 to a minimum value close to 0 but the super-quantum discord and quantum discord vanish. This is contrary to recent results obtained.
