Out-of-time-order correlators and quantum phase transitions in the Rabi and Dicke model
Zheng-Hang Sun, Jia-Qi Cai, Qi-Cheng Tang +2
The out-of-time-order correlators (OTOCs) is used to study the quantum phase transitions (QPTs) between the normal phase and the superradiant phase in the Rabi and few-body Dicke m…

Enhancing the geometric quantum discord in the Heisenberg {\it XX} chain by Dzyaloshinsky-Moriya interaction
Jia-Min Gong, Qi Tang, Yu-Hang Sun +1
We studied the trance distance, the Hellinger distance, and the Bures distance geometric quantum discords (GQDs) for a two-spin Heisenberg {\it XX} chain with the Dzyaloshinsky-Mor…
