Spin Squeezing, Negative Correlations, and Concurrence in the Quantum Kicked Top Model
Xiaoqian Wang, Jian Ma, Lijun Song +2
We study spin squeezing, negative correlations, and concurrence in the quantum kicked top model. We prove that the spin squeezing and negative correlations are equivalent for spin…

Entanglement conditions for tripartite systems via indeterminacy relations
Lijun Song, Xiaoguang Wang, Dong Yan +1
Based on the S-R indeterminacy relations in conjugation with the partial transposition, we derive a class of inequalities for detecting entanglement in several tripartite systems,…
