标题： Annular billiard dynamics in a circularly polarized strong laser field

摘要： 我们通过将富勒烯分子（C60）的价电子的动力学建模为环形台球中的经典粒子运动，分析了其在圆偏振激光场作用下的动力学行为。 我们表明，台球模型的相空间会产生三种不同的轨迹："耳语走廊轨道"，这些轨道仅撞击外壁，"雏菊轨道"，这些轨道撞击两个台球壁（同时始终仅顺时针或逆时针旋转），以及仅相对于激光项测量的下场部分的轨道。 一般来说，这些轨迹在强度从10^10到10^14 W*cm^-2增加时，仍保持其独特的特征。 我们将相空间的这种稳健分离归因于无扭转环面的存在。 显示英文摘要

摘要： We analyze the dynamics of a valence electron of the buckminsterfullerene molecule (C60) subjected to a circularly polarized laser field by modeling it with the motion of a classical particle in an annular billiard. We show that the phase space of the billiard model gives rise to three distinct trajectories: "Whispering gallery orbits", which only hit the outer billiard wall, "daisy orbits" which hit both billiard walls (while rotating solely clockwise or counterclockwise for all time), and orbits which only visit the downfield part of the billiard, as measured relative to the laser term. These trajectories, in general, maintain their distinct features, even as intensity is increased from 10^10 to 10^14 W*cm^-2. We attribute this robust separation of phase space to the existence of twistless tori.
