Figure 2

The Bose-Josephson dynamics of the dressed states for non-interacting BEC. (ac) The simulation results of Josephson oscillations via the CGPEs [Eq. (5)] for different coupling strength Ω. The figures in the first (second) row are the time evolution of the density profiles for upper (lower) dressed state, denoted by \({{\rm{\Psi }}}_{+}\) (\({{\rm{\Psi }}}_{-}\)). (df) The simulation results of Josephson oscillations for lower dressed state Ψ , calculated by the decoupled equations [Eq. (7)] for different coupling strength Ω. The initial state is set as the located state of the right well of the lower dressed potential, namely Ψ(x, t = 0) = ϕ1(x) and Ψ+(x, t = 0) = 0, see Fig. 1(b) (I). Other parameters: atom number N = 10000, interaction strength g = 0, potential separation x0 = 3.
