Quantum-Fluctuation-Driven Coherent Spin Dynamics in Small Condensates
Xiaoling Cui, Yupeng Wang, Fei Zhou
We have studied quantum spin dynamics of small condensates of cold sodium atoms. For a condensate initially prepared in a mean field ground state, we show that coherent spin dynami…

Intrinsic relation between ground-state fidelity and the characterization of a quantum phase transition
Shu Chen, Li Wang, Yajiang Hao +1
The notion of fidelity in quantum information science has been recently applied to analyze quantum phase transitions from the viewpoint of the ground state (GS) overlap for various…

Fidelity and Quantum phase transition for the Heisenberg chain with the next-nearest-neighbor interaction
Shu Chen, Li Wang, Shi-Jian Gu +1
In this paper, we investigate the fidelity for the Heisenberg chain with the next-nearest-neighbor interaction (or the model) and analyze its connections with quantum pha…
