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…
