Electron Odd-Pearcey Gaussian Beams Propagating In a Constant Magnetic Field

In this paper, the introduction of a novel type of electron beams known as electron odd-Pearcey Gaussian beams (EOPGBs) is presented. For the first time, the dynamics of EOPGBs are explored propagating in both free space and a constant magnetic field by employing the Schrodinger equation. The investigation reveals that the electron beams exhibit remarkable auto-focusing characteristics in these two media, and the focal length can be controlled by adjusting certain parameters. Additionally, in a constant magnetic field, EOPGBs exhibit intriguing properties, notably the dual auto-focusing property, which sets them apart from other known electron beams. The probability currents and distribution factors are used to provide a theoretical explanation for the aforementioned features of EOPGBs. Furthermore, the conclusions are consistent with the results obtained from numerical simulations. The paper presents the introduction of a novel type of electron beams.
