Entanglement Creation and Storage in Two Qubits Coupling to an Anisotropic Heisenberg Spin Chain
Chunlei Zhang, Shiqun Zhu, Jie Ren
The time evolution of the entanglement of a pair of two spin qubits is investigated when the two qubits simultaneously couple to an environment of an anisotropic Heisenberg XXZ spi…
Entanglement Entropy in an Antiferromagnetic Heisenberg Spin Chain with Boundary Impurities
Jie Ren, Shiqun Zhu, Xiang Hao
The effects of boundary impurities on the entanglement entropy in an antiferromagnetic Heisenberg opened spin- chain are investigated. The method of density-matrix renormaliza…
Quantum phase transition in easy-axis antiferromagnetic Heisenberg spin-1 chain
Jie Ren, Shiqun Zhu
The fidelity and entropy in an easy-axis antiferromagnetic Heisenberg spin-1 chain are studied numerically. By using the method of density-matrix renormalization group, the effects…
The entanglement dynamics of interacting qubits embedded in a spin environment with Dzyaloshinsky-Moriya term
Wen-Long You, Yu-Li Dong
We investigate the entanglement dynamics of two interacting qubits in a spin environment, which is described by an XY model with Dzyaloshinsky-Moriya (DM) interaction. The competin…
