Quantum entanglement approaching with concurrence in the presence of chaos

The concept of concurrence is researched to characterize the dynamical behavior of the bipartite systems. The quantum kicked top model has great significance in the qubit systems and the chaotic properties of the entanglement. The eigenvalues of the reduced symmetric density matrix are determined, it allows us to understand this driven system to distinguish between regularity and chaoticity dynamics in the finite simulation, which depend on the strength excitation in the framework of the concurrence.
