英文摘要	We investigate the quantum transport dynamics of periodically delta-kicked Bose-Einstein condensate under the effect of spatially modulated nonlinear interactions. The spatial modulation frequency can dramatically affect the transport behaviors of the ultra-cold atoms. For odd frequency, the linear growth of the directed current is close to that of the noninteracting case for not very strong nonlinear interaction. Both the acceleration and the quantum state evolution gradually approach that of the noninteracting case with increasing frequency. For other values of frequency, a very weak nonlinear interaction can dramatically reduce the linear growth of the directed current. The quantum state evolution differs rapidly from that of the noninteracting case. The underlying dynamic mechanism is uncovered and some important implications are addressed.; National Basic Research Program of China (973 Program) [2013CBA01502, 2011CB921503, 2013CB834100]; National Natural Science Foundation of China [11447016, 11374040, 11274051, 11475027]; SCI(E); EI; ARTICLE; liu_jie@iapcm.ac.cn; lbfu@iapcm.ac.cn; 12; 49
