摘要:

强激光电离扩展了爱因斯坦的光电效应规则,在过去的几十年里得到了广泛的研究。到目前为止,在所有情况下,光子都被假定携带一个单位的角动量。然而,现在很清楚,光子可以拥有额外的角动量,轨道角动量(OAM),与它们的空间分布有关。我们展示了一个完整的描述OAM光子的光电离,包括新的选择规则,涉及一个以上的角动量单位。我们从理论上探讨了位于承载OAM的强紫外光束中心的单个电子原子的相互作用,设想了量子光学的新场景。

英文摘要:

Intense laser ionization expands Einstein's photoelectric effect rules giving a wealth of phenomena widely studied over the last decades. In all cases, so far, photons were assumed to carry one unit of angular momentum. However it is now clear that photons can possess extra angular momentum, the orbital angular momentum (OAM), related to their spatial profile. We show a complete description of photoionization by OAM photons, including new selection rules involving more than one unit of angular momentum. We explore theoretically the interaction of a single electron atom located at the center of an intense ultraviolet beam bearing OAM, envisaging new scenarios for quantum optics.
