安德森和动力学局域化已被实验观察到与超冷原子物质。Feshbach共振用于有效地控制原子之间的相互作用强度。这使得研究局域波包的相互作用的离域效应。离域过程是亚扩散和缓慢的，从而限制了定量的实验和数值分析。我们提出了一个优雅的解决方案的问题，适当的斜坡的相互作用强度的时间。我们证明，亚扩散加速到正常的扩散相互作用的无序和踢原子系统。实验测试这些理论结果的大门是敞开的，并在更高的空间维度中攻击类似的计算任务
Anderson and dynamical localization have been experimentally observed with ultra-cold atomic matter. Feshbach resonances are used to efficiently control the strength of interactions between atoms. This allows to study the delocalization effect of interactions for localized wave packets. The delocalization processes are subdiffusive and slow, thereby limiting the quantitative experimental and numerical analysis. We propose an elegant solution of the problem by proper ramping the interaction strength in time. We demonstrate that subdiffusion is speeded up to normal diffusion for interacting disordered and kicked atomic systems. The door is open to test these theoretical results experimentally, and to attack similar computational quests in higher space dimensions
