Atomic Entanglement vs Photonic Visibility for Quantum Criticality of Hybrid System
M. X. Huo, Ying Li, Z. Song +1
To characterize the novel quantum phase transition for a hybrid system consisting of an array of coupled cavities and two-level atoms doped in each cavity, we study the atomic enta…
Decay of Loschmidt Echo Enhanced by Quantum Criticality
H. T. Quan, Z. Song, X. F. Liu +2
We study the transition of a quantum system from a pure state to a mixed one, which is induced by the quantum criticality of the surrounding system coupled to it. To chara…
Characterizing entanglement by momentum-jump in the frustrated Heisenberg ring at quantum phase transition
Xiao-Feng Qian, Tao Shi, Ying Li +2
We study the pairwise concurrences, a measure of entanglement, of the ground states for the frustrated Heisenberg ring to explore the relation between entanglement and quantum phas…
Quantum state transfer via the ferromagnetic chain in a spatially modulated field
T. Shi, Ying Li, Z. Song +1
We show that a perfect quantum state transmission can be realized through a spin chain possessing a commensurate structure of energy spectrum, which is matched with the correspondi…
