Landau-Zener dynamics. (a,b) Time evolution of the density profile and the population for the upper (lower) dressed state, labeled by \({{\rm{\Psi }}}_{+}\) (\({{\rm{\Psi }}}_{-}\)), obtained by solving the CGPEs [Eq. (5)]. The initial state is set as a wave packet in lower dressed state centering at a position away from the minimum of the right well of the lower dressed potential with a distance xd, namely, Ψ(x, t = 0) = ϕ1(x − xd) and Ψ+(x, t = 0) = 0; see Fig. 1(b) (II). The coupling strength is Ω = 3. (c) Non-adiabatic transition probability P obtained from the original CGPEs [Eq. (5)] (dots) and the LZ formula [Eq. (23)] (solid lines) for different coupling strength Ω and xd. Other parameters: interaction strength g = 0, potential separation x0 = 3.
