Factorization Law for Two Lower Bounds of Concurrence
Sayyed Yahya Mirafzali, Iman Sargolzahi, Ali Ahanj +2
We study the dynamics of two lower bounds of concurrence in bipartite quantum systems when one party goes through an arbitrary channel. We show that these lower bounds obey the fac…

Thermal entanglement in a two-qutrit system with nonlinear coupling under nonuniform external magnetic field
Iman Sargolzahi, Sayyed Yahya Mirafzali, Mohsen Sarbishaei
We study the thermal entanglement of a 2-qutrit spin chain with nonlinear coupling in the presence of nonuniform magnetic field. Thermal entanglement of an arbitrary (finite dimens…
