The proposed activities build on past efforts to study the few body dynamics of atoms by the direct solution of the time-dependent Schrodinger equation on a numerical lattice. Theoretical and mputational efforts will address the dynamics of continuum and Rydberg states in few-body atomic and molecular systems. A variety of massively parallel computing platforms are used to provide quantitatively accurate cross sections for processes involving three body breakup as well as for studying Bose condensates in the presence of external perturbations.

拟议的活动建立在过去通过直接求解数值晶格上的随时间变化的薛定谔方程来研究原子的少数体动力学的努力的基础上。理论和计算的努力将解决在少体原子和分子系统的连续和里德堡态的动力学。各种各样的大规模并行计算平台被用来提供定量准确的横截面的过程，涉及三体分裂，以及研究玻色凝聚在外部扰动的存在下。
