Rydberg-atom acceleration with pulsed Pearcey beams

A novel approach is proposed for accelerating Rydberg atoms utilizing two-dimensional Pearcey beams instead of traditional circular symmetric beams such as Gaussian beams. The structure of the two-dimensional Pearcey optical field can achieve quasi-unidirectional acceleration of atoms within a small spot size, which is conducive to improving the detection efficiency. In addition, the self-focusing characteristic of this beam can significantly reduce the required intensity of the driving source compared to the traditional scheme using the Gaussian beams.
