Entanglement induced in spin-1/2 particles by a spin chain near its critical points
X. X. Yi, H. T. Cui, L. C. Wang
A relation between entanglement and criticality of spin chains is established. The entanglement we exploit is shared between auxiliary particles, which are isolated from each other…
Entanglement of Fermi gases in a harmonic trap
X. X. Yi
For both cases with and without interactions, bipartite entanglement of two-fermions from a Fermi gas in a trap is investigated. We show how the entanglement depends on the locatio…
Entanglement distillation using particle statistics
H. L. Huang, L. H. Cheng, X. X. Yi
We extend the idea of entanglement concentration for pure states(Phys. Rev. Lett. {\bf 88}, 187903) to the case of mixed states. The scheme works only with particle statistics and…
Quantum trajectory approach to the geometric phase: open bipartite systems
X. X. Yi, D. P. Liu, W. Wang
Through the quantum trajectory approach, we calculate the geometric phase acquired by a bipartite system subjected to decoherence. The subsystems that compose the bipartite system…
Entangling Two-Atom Through Cooperative Interaction Under Stimulated Emission
Y. Q. Guo, H. S. Song, L. Zhou +1
We discuss the generation of two-atom entanglement inside a resonant microcavity under stimulated emission (STE) interaction. The amount of entanglement is shown based on different…
Geometric Phase in Entangled Bipartite Systems
H. T. Cui, L. C. Wang, X. X. Yi
The geometric phase (GP) for bipartite systems in transverse external magnetic fields is investigated in this paper. Two different situations have been studied. We first consider t…
