Large amplitude relativistic electromagnetic solitons due to strong photon-condensation in intense laser underdense homogeneous collisionless plasma interaction

Large amplitude electromagnetic solitons due to strong photon condensation, induced by a linearly polarized intense laser interacting with an underdense uniform collisionless plasma, are studied by particle simulations. In homogeneous plasma, both standing and accelerated solitons are observed. It i...

Description
Summary:Large amplitude electromagnetic solitons due to strong photon condensation, induced by a linearly polarized intense laser interacting with an underdense uniform collisionless plasma, are studied by particle simulations. In homogeneous plasma, both standing and accelerated solitons are observed. It is found that the acceleration of the solitons depends upon not only the laser amplitude but also the plasma length. The electromagnetic frequency of the solitons is between half and one time of the unperturbed electron plasma frequency. The electrostatic field inside the soliton has a one-cycle structure in space, while the transverse electric and the magnetic fields have half- and one-cycle structures, respectively. The acceleration of the solitons is briefly discussed.
