Mutual information and swap operation in the two-qubit Heisenberg model with Dzyaloshinskii-Moriya anisotropic antisymmetric interaction
Guo-Feng Zhang
Mutual information and swap operation in the two-qubit Heisenberg model with the Dzyaloshinskii-Moriya (DM) anisotropic antisymmetric interaction are investigated. It is found that…
The swap operation in the two-qubit Heisenberg XXZ model-effects of anisotropy and magnetic field
Yue Zhou, Guo-Feng Zhang, Fu-Hua Yang +1
In this paper we study the swap operation in a two-qubit anisotropic XXZ model in the presence of an inhomogeneous magnetic field. We establish the range of anisotropic parameter w…
Entangled quantum heat engines based on two two-spin systems with Dzyaloshinski-Moriya anisotropic antisymmetric interaction
Guo-Feng Zhang
We construct an entangled quantum heat engine (EQHE) based on two two-spin systems with Dzyaloshinski-Moriya (DM) anisotropic antisymmetric interaction. By applying the explanation…
Geometric phase of a bipartite system with Dzyaloshinski-Moriya interaction
Yue Zhou, Guo-Feng Zhang
The Berry phase of a bipartite system described by a Heisenberg XXZ model driven by a one-site magnetic field is investigated. The effect of the Dzyaloshinski-Moriya (DM) anisotrop…
Thermal entanglement in a two-qubit Heisenberg XXZ spin chain under an inhomogeneous magnetic field
Guo-Feng Zhang
The thermal entanglement in a two-qubit Heisenberg \emph{XXZ} spin chain is investigated under an inhomogeneous magnetic field \emph{b}. We show that the ground-state entanglement…
