Bound state and Localization of excitation in many-body open systems
H. T. Cui, H. Z. Shen, S. C. Hou +1
Bound state and time evolution for single excitation in one dimensional XXZ spin chain within non-Markovian reservoir are studied exactly. As for bound state, a common feature is t…
Detecting ground-state degeneracy in many-body systems through qubit decoherence
H. T. Cui, X. X. Yi
By coupling with a qubit, we demonstrate that qubit decoherence can unambiguously detect the occurrence of ground-state degeneracy in many-body systems. We first demonstrate univer…
A Generalized Geometric Measurement of Quantum Discord: Exact Treatment
Hai-Tao Cui, Jun-Long Tian, Gui Yang
A generalization of the geometric measure of quantum discord is introduced in this article, based on Hellinger distance. Our definition has virtues of computability and independenc…
Topology of Entanglement in Multipartite States with Translational Invariance
H. T. Cui, J. L. Tian, C. M. Wang +1
The topology of entanglement in multipartite states with translational invariance is discussed in this article. Two global features are foundby which one can distinguish distinct s…
Maximal Overlap with a Fully Separable State and Translational Invariance in Multipartite Entangled States
H. T. Cui, Di Yuan, J. L. Tian
The maximal overlap with the fully separable state for the multipartite entangled pure state with translational invariance is studied explicitly by some exact and numerical evaluat…
Geometric Entanglement in Valance-Bond-Solid state
H. T. Cui, C. M. Wang, S. Z. Yuan
Multipartite entanglement, measured by the geometric entanglement(GE), is discussed for integer spin Valance-Bond-Solid (VBS) state respectively with periodic boundary condition(PB…
