Koch It is proposed to study simple atoms, hydrogen and helium, in strong electromagnetic fields consisting of one frequency or two frequencies, without or with added stochastic components (noise). Its objective is to understand periodically driven quantal systems whose classical counterpart is chaotic, thus addressing questions in the interdisciplinary area of quantum chaos. New experiments will make a detailed investigation into the effect of stochastic components (noise) added to the strong oscillatory microwave fields. A new program of research will investigate the detailed behavior of low-pressure, dc-biased, radio-frequency gas discharges as a nonlinear dynamical system.

Koch建议研究由一个频率或两个频率组成的强电磁场中的简单原子，氢和氦，没有或有附加的随机分量(噪声)。它的目标是理解周期驱动的量子系统，其经典对应系统是混沌的，从而解决量子混沌跨学科领域的问题。新的实验将详细研究随机分量(噪声)对强振荡微波场的影响。一项新的研究计划将调查低压、直流偏置、射频气体放电的详细行为，将其作为一个非线性动力学系统。
