强Laser场中单电子波包的光致发射

Photo-Emission of a Single-Electron Wave-Packet in a Strong Laser Field

Justin Peatross, Carsten Müller, Karen Z. Hatsagortsyan, Christoph H. Keitel

摘要:

研究了单电子波包在强激光场中的辐射。通过电子的维格纳函数,建立了精确的量子公式和经典公式之间的关系。特别是,我们表明,波包,即使当它传播到驱动激光场的波长的规模,不能被视为一个扩展的经典电荷分布,而是作为一个点样发射器携带信息的初始量子态的行为。我们概述了一个实验装置,致力于把这个结论的测试。

英文摘要:

The radiation emitted by a single-electron wave packet in an intense laser field is considered. A relation between the exact quantum formulation and its classical counterpart is established via the electron's Wigner function. In particular we show that the wave packet, even when it spreads to the scale of the wavelength of the driving laser field, cannot be treated as an extended classical charge distribution but rather behaves as a point-like emitter carrying information on its initial quantum state. We outline an experimental setup dedicated to put this conclusion to the test.
