abstract = "Bose-Einstein condensates loaded into kicked optical lattices can be treated as quantum kicked-rotor systems. Noninteracting rotors show dynamical localization in momentum space. The experimentally tunable condensate interaction is included in a qualitative Gross-Pitaevskii-type model based on two-body interactions. We observe strong- and weak-chaos regimes of wave packet spreading in momentum space. In the intermediate strong-chaos regime the condensate energy grows as t(1/2). In the asymptotic weak-chaos case the growth crosses over into a t(1/3) law. The results do not depend on the details of the kicking. Copyright (C) EPLA, 2011",
