ClassSTRONG: Classical simulations of strong field processes

Abstract
A set of Mathematica functions is presented to model classically two of the most important processes in strong field physics, namely high-order harmonic generation (HHG) and above-threshold ionization (ATI). Our approach is based on the numerical solution of the Newton–Lorentz equation of an electron moving on an electric field and takes advantage of the symbolic languages features and graphical power of Mathematica. Like in the Strong Field Approximation (SFA), the effects of atomic potentia...

Nature of problem
The Mathematica functions model high-order harmonic generation (HHG) and above-threshold ionization (ATI) using the classical equations of motion of an electron moving in an oscillating electric field. In Strong Field Physics HHG and ATI represent two of the most prominent examples of the nonperturbative interaction between strong laser sources and matter. In HHG an atomic or molecular bound electron is put into the continuum by the external laser electric field. Due to the oscillatory nature of ...

摘要：本文提出一组Mathematica函数，用于经典建模强场物理中两类最为重要的过程：即高次谐波产生（high-order harmonic generation, HHG）与阈上电离（above-threshold ionization, ATI）。本方法基于对电场中运动电子的牛顿-洛伦兹方程进行数值求解，并充分利用Mathematica的符号语言特性与图形化处理能力。与强场近似（Strong Field Approximation, SFA）中类似，原子势的作用……

问题本质：本套Mathematica函数通过求解振荡电场中运动电子的经典运动方程，实现对高次谐波产生（HHG）与阈上电离（ATI）的建模。在强场物理学领域，HHG与ATI是强激光源与物质之间非微扰相互作用的两类最具代表性的实例。在HHG过程中，原子或分子的束缚电子会在外源激光电场的作用下脱离束缚进入连续态。由于其振荡特性的……
