Dynamical multipartite entanglement in a generalized Tavis-Cummings model with XY spin interaction
Yuguo Su, Zhijie Sun, Yiying Yan +5
Multipartite entanglement is a long-term pursuit in the resource theory, offering a potential resource for quantum metrology. Here, we present the dynamical multipartite entangleme…

Spin squeezing and concurrence under Lee-Yang dephasing channels
Yuguo Su, Hongbin Liang, Xiaoguang Wang
The Lee-Yang zeros are one-to-one mapping to zeros in the coherence of a probe spin coupled to a many-body system. Here, we study the spin squeezing under two different types of Le…
