Abstract

The quantum vortices formed as a result of barrier-suppression ionization of a two-dimensional hydrogen atom by an ultrashort laser pulse are theoretically investigated. Using an analytical expression for the wave function of a photoelectron in the momentum representation, the probability flux density is investigated. In this case, both the standard definition of a flux and an alternative “symmetrical” one are used. The latter, due to the sensitivity to the phase of the wave function, makes it possible to identify quantum vortices in the momentum space.

动量空间量子漩涡的识别

摘要从理论上研究了二维氢原子在超短激光脉冲的阻遏电离作用下形成的量子漩涡。利用动量表示法中光电子波函数的解析表达式，研究了概率通量密度。在这种情况下，既使用了通量的标准定义，也使用了另一种 "对称 "定义。后者由于对波函数相位的敏感性，使得识别动量空间中的量子漩涡成为可能。
