A General Scenario of Tunneling Time in Different Energy Regimes
Sheng-Chang Li
We theoretically study the tunneling time by investigating a wave packet of Bose-condensed atoms passing through a square barrier. We find that the tunneling time exhibits differen…
W-shaped solitons generated from a weak modulation in the Sasa-Satsuma equation
Li-Chen Zhao, Sheng-Chang Li, Liming Ling
We revisit on rational solution of Sasa-Satsuma equation, which can be used to describe evolution of optical field in a nonlinear fiber with some high-order effects. We find a stri…
Rational W-shaped Optical Soliton on Continuous Wave in Presence of Kerr Dispersion and Stimulated Raman Scattering
Li-Chen Zhao, Sheng-Chang Li, Liming Ling
We study localized wave on continuous wave background analytically in a nonlinear fiber with higher order effects such as higher order dispersion, Kerr dispersion, and stimulated i…
Quantum phase transition in a three-level atom-molecule system
Sheng-Chang Li, Li-Bin Fu, Fu-Li Li
We adopt a three-level bosonic model to investigate the quantum phase transition in an ultracold atom-molecule conversion system which includes one atomic mode and two molecular mo…
Nonlinear Ramsey interferometry with the Rosen-Zener pulses on a two-component Bose-Einstein condensate
Sheng-Chang Li, Li-Bin Fu, Wen-Shan Duan +1
We propose a feasible scheme to realize nonlinear Ramsey interferometry with a two-component Bose-Einstein condensate, where the nonlinearity arises from the interaction between co…
