Slowly moving matter-wave gap soliton propagation in weak random optical lattices

Zhang, M. R.; Jiang, X. Y.; Zhang, Y. L.; Shi, L.; Zi, J.; … - In: The European Physical Journal B - Condensed Matter and … 58 (2007) 3, pp. 269-278

We systematically investigate slowly moving matter-wave gap soliton propagation in weak random optical lattices. With the weak randomness, an effective-particle theory is constructed to show that the motion of a gap soliton is similar to a particle moving in random potentials. Based on the...
