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…

Quantum dynamics of repulsively bound atom pairs in the Bose-Hubbard model
Li Wang, Yajiang Hao, Shu Chen
We investigate the quantum dynamics of repulsively bound atom pairs in an optical lattice described by the periodic Bose-Hubbard model both analytically and numerically. In the str…
