In this work, it is shown that Weyl particles can exist at different states in zero electromagnetic field, either as free particles or at localized states. In addition, it is shown that the localization, as well as the energy, of the particles can be fully controlled using simple electric fields, which can easily be realized in practice. These results are particularly important regarding possible practical applications of Weyl particles, both considering solid‐state physics in materials supporting these particles and laser physics using ions trapped by laser beams, which can simulate the behavior of Weyl particles.
The main results of this work are the following: 1) Weyl particles can exist at different states in zero electromagnetic field, either as free particles, or at localized states. 2) The localization, as well as the energy, of the particles can be fully controlled using simple electric fields, which can be easily realized in practice.
