The effects of nonlinear couplings and external magnetic field on the thermal entanglement in a two-spin-qutrit system
Guo-feng Zhang, Shu-shen Li
We investigate the effects of nonlinear couplings and external magnetic field on the thermal entanglement in a two-spin-qutrit system by applying the concept of negativity. It is f…

Thermal entanglement in a two-spin-qutrit system under a nonuniform external magnetic field
Guo-Feng Zhang, Shu-Shen Li
The thermal entanglement in a two-spin-qutrit system with two spins coupled by exchange interaction under a magnetic field in an arbitrary direction is investigated. Negativity, th…

Noiseless method for checking the Peres separability criterion by local operations and classical communication
Yan-Kui Bai, Shu-Shen Li, Hou-Zhi Zheng
We present a method for checking Peres separability criterion in an arbitrary bipartite quantum state within local operations and classical communication scenario. The met…
