Entanglement evolution of a two-qubit system with decay beyond rotating-wave approximation
Qing Yang, Ming Yang, Da-Chuang Li +1
Two noninteracting atoms, initially entangled in Bell states, are coupled to a one-mode cavity. Based on the reduced non-perturbative quantum master equation, the entanglement evol…

Effect of different Dzyaloshinskii-Moriya interactions on entanglement in the Heisenberg XYZ chain
Da-Chuang Li, Zhuo-Liang Cao
In this paper, we study the thermal entanglement in a two-qubit Heisenberg XYZ system with different Dzyaloshinskii-Moriya (DM) couplings. We show that different DM coupling parame…

Thermal entanglement in the anisotropic Heisenberg XXZ model with the Dzyaloshinskii-Moriya interaction
Da-Chuang Li, Xian-Ping Wang, Zhuo-Liang Cao
The thermal entanglement is investigated in a two-qubit Heisenberg XXZ system with Dzyaloshinskii-Moriya (DM) interaction. It is shown that the entanglement can be efficiently cont…
