Nonlocal correlations for manifold quantum systems: Entanglement of two-spin states
K. Berrada, A. Mohammadzade, S. Abdel-Khalek +2
In this paper, we study the bipartite entanglement of spin coherent states in the case of pure and mixed states. By a proper choice of the subsystem spins, the entanglement for lar…

Entanglement Sudden Death and Sudden Birth in Semiconductor Microcavities
S. Abdel-Khalek, Sh. Barzanjeh, H. Eleuch
We explore the dynamics of the entanglement in a semiconductor cavity QED containing a quantum well. We show the presence of sudden birth and sudden death for some particular sets…
