Dispersion Control for Matter Waves and Gap Solitons in Optical Superlattices

Louis, P J Y; Ostrovskaya, Elena; Kivshar, Yuri


We present a numerical study of dispersion manipulation and formation of matter-wave gap solitons in a Bose-Einstein condensate trapped in an optical superlattice. We demonstrate a method for controlled generation of matter-wave gap solitons in a stationary lattice by using an interference pattern of two condensate wave packets, which mimics the structure of the gap soliton near the edge of a spectral band. The efficiency of this method is compared to that of gap soliton generation in a moving...[Show more]
