英文摘要	We investigate the quantum transport dynamics governed by the nonlinear Schrodinger equation with a periodically-delta-kicking potential and discover the emergence of a directed current in momentum space. With the increase of nonlinearity, we find strikingly that the momentum current decreases, reverses, and finally vanishes, indicating that the quantum transport can be effectively manipulated through adjusting the nonlinearity. The underlying dynamic mechanism is uncovered and some important implications are addressed.; Physics, Fluids & Plasmas; Physics, Mathematical; SCI(E); EI; 0; ARTICLE; lbfu@iapcm.ac.cn; liu_jie@iapcm.ac.cn; 2; 90
