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…
One-dimensional fermionic gases with attractive p-wave interaction in a hard-wall trap
Yajiang Hao, Yunbo Zhang, Shu Chen
We investigate the ground state of the one-dimensional fermionic system enclosed in a hard-wall trap with attractive contact p-wave interactions. Based on the Bethe ansatz method,…
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…
Numerical Simulation on Tunnel Splitting of Bose-Einstein Condensate in Multi-Well Potentials
Yajiang Hao, J. -Q. Liang, Yunbo Zhang
The low-energy-level macroscopic wave functions of the Bose-Einstein condensate(BEC) trapped in a symmetric double-well and a periodic potential are obtained by solving the Gross-P…
