Bose Einstein

By developing a multiple-scale method, we study analytically the dynamics of the soliton inside the semi-infinite band gap (SIBG) of quasi-one-dimensional Bose–Einstein condensates trapped in an optical lattice. In the linear case, a stable condition of soliton formation is obtained. For a weak nonlinearity, whether there occurs a spatially propagating or localized gap soliton is determined by the lattice depth. Meanwhile, we predict the existence of the dark (bright) gap solitons for the repulsive (attractive) interactions in the SIBG, different from that of the gap solitons in other energy gaps. And the collision of two dark (or bright) solitons is nearly elastic under a safe range of atomic numbers. An experimental protocol is further designed for observing these phenomena.

Lower Cutoff

For a one-dimensional damped and parametrically driven diatomic-like macro-pendulum lattice, five types of the lower cutoff and upper cutoff stable soliton and kink excitations have been observed. Especially, the gap soliton which has been studied widely in physics is first observed in macro-experiments. The experimental results can be well explained qualitatively by a nonlinear Schrödinger theory after neglecting the nonuniformity effects of the pendulums.
