Abstract

We show that dimensional scaling, combined with the high-frequency Floquet theory, provides useful means to evaluate the stability of gas phase atomic anions in a superintense laser field. At the large-dimension limit (D-->infinity), in a suitably scaled space, electrons become localized along the polarization direction of the laser field. We find that calculations at large D are much simpler than D=3, yet yield similar results for the field strengths needed to bind an "extra" one or two electrons to H and He atoms. For both linearly and circularly polarized laser fields, the amplitude of quiver motion of the electrons correlates with the detachment energy. Despite large differences in scale, this correlation is qualitatively like that found between internuclear distances and dissociation energies of chemical bonds.

摘要

我们表明,维度缩放与高频弗洛凯理论相结合,为评估超强激光场中气相原子阴离子的稳定性提供了有用的方法。在大维度极限(D→∞)下,在适当缩放的空间中,电子沿激光场的偏振方向局域化。我们发现,在大D时的计算比D = 3时简单得多,但对于将“额外”的一个或两个电子束缚到H和He原子所需的场强,却能得出相似的结果。对于线偏振和圆偏振激光场,电子的颤动运动幅度与脱离能相关。尽管尺度差异很大,但这种相关性在定性上类似于化学键的核间距和解离能之间的相关性。
