扭曲光离子相互作用：纵向场的作用
Twisted-ligth--ion interaction: the role of longitudinal fields
摘要：
光束的传播是很好地描述使用傍轴近似，沿传播方向的场分量通常被忽略。然而，对于强烈不均匀或成形的光场，这种近似可能会失败，导致光-物质相互作用的有趣变化。这是具有相反的轨道和自旋角动量的扭曲光的情况。我们比较了Schmiegelow等人，Nat.通信\ 7，12998（2016），其中考虑了电场的纵向分量的完整模型。我们的模型符合实验数据，并排除了11个标准偏差的近似完整的横向场。这证明了所有场分量在扭曲光与物质相互作用中的重要性。
英文摘要：
The propagation of light beams is well described using the paraxial approximation, where field components along the propagation direction are usually neglected. For strongly inhomogeneous or shaped light fields, however, this approximation may fail, leading to intriguing variations of the light-matter interaction. This is the case of twisted light having opposite orbital and spin angular momenta. We compare experimental data for the excitation of a quadrupole transition in a single trapped $^{40}$Ca$^+$ ion by Schmiegelow et al, Nat.\ Comm.\ 7, 12998 (2016), with a complete model where longitudinal components of the electric field are taken into account. Our model matches the experimental data and excludes by 11 standard deviations the approximation of complete transverse field. This demonstrates the importance of all field components in the interaction of twisted light with matter.
