Spin Hall effect in the kagome lattice with Rashba spin-orbit interaction
Guocai Liu, Ping Zhang, Zhigang Wang +1
We study the spin Hall effect in the kagomé lattice with Rashba spin-orbit coupling. The conserved spin Hall conductance (see text) and its two components, i.e., the c…
Disentanglement of two qubits coupled to an XY spin chain: Role of quantum phase transition
Zi-Gang Yuan, Ping Zhang, Shu-Shen Li
We study the disentanglement of two spin qubits which interact with a general XY spin-chain environment. The dynamical process of the disentanglement is numerically and analyticall…
Detecting a set of entanglement measures in an unknown tripartite quantum state by local operations and classical communication
Yan-Kui Bai, Shu-Shen Li, Hou-Zhi Zheng +1
We propose a more general method for detecting a set of entanglement measures, i.e. negativities, in an \emph{arbitrary} tripartite quantum state by local operations and classical…
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…
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…
Photoluminescence pressure coefficients of InAs/GaAs quantum dots
Jun-Wei Luo, Shu-Shen Li, Jian-Bai Xia +1
We have investigated the band-gap pressure coefficients of self-assembled InAs/GaAs quantum dots by calculating 17 systems with different quantum dot shape, size, and alloying prof…
