Two-qutrit Nonorthogonal Systems and their Entanglement Dynamics under XX Hamiltonian and DM Interaction

In this work, we study entanglement dynamics in a two-qutrit systemunder the XX Hamiltonian, in the presence of Dzyaloshinskii-Moriya interaction and external magnetic field. Using the generalized concurrence as an entanglement measure, their entanglement dynamics are investigated by numerical computation and the appropriate graphs as a function of the parameters are depicted. The generalized concurrence measure changes for different values of interaction and non-phase coherence parameters can be investigated. It is observed that the entanglement dynamics variations range of these states is changed between maximum entanglement or no entanglement in qutrit systems, depending on the choice of the parameters involved.
