Perturbation of Coulomb Orbits (Physics)

在经典和量子随机动力学的框架下，研究了在多重散射和动态屏蔽效应的影响下，密集介质中激发态的演化。目前的应用和与实验的比较主要集中在原子或离子在固体中的渗透。其基本目的是从输运理论的角度分析简单原子系统的噪声诱导动力学。密集介质中强扰动原子态的演化与非线性动态介质中的随机过程理论有关。为了研究由随机力(噪声)引起的外在随机性和(经典)混沌动力学引起的内在随机性之间的相互作用，将进行经典和量子计算。//

It is proposed to study the evolution of excited atomic states in dense media, under the influence of multiple scattering and dynamical screening effects, within the framework of classical and quantum stochastic dynamics. Present applications and comparisons with experiment focus primarily on atom or ion penetration through solids. The fundamental goal is to analyze noise induced dynamics of simple atomic systems in terms of transport theory. Evolution of atomic states strongly perturbed in dense media will be related to the theory of stochastic processes in non-linear dynamic media. Both classical and quantum calculations will be performed, in order to study the interplay of extrinsic stochasticity due to random forces (noise) and intrinsic stochasticity due to (classically) chaotic dynamics. //
