Three Dimensional Relativistic Electromagnetic Sub-cycle Solitons
Abstract
We present the results of a three dimensional simulation of laser induced sub-cycle relativistic electromagnetic soliton. Three dimensional (3D) relativistic electromagnetic sub-cycle solitons were observed in 3D PIC simulations of an intense short laser pulse propagation in an underdense plasma. Their structure resembles that of an oscillating electric dipole with a poloidal electric field and a toroidal magnetic field that oscillate in-phase with the electron density with frequency below the Langmuir frequency. On the ion time scale the soliton undergoes a Coulomb explosion of its core, resulting in ion acceleration, and then evolves into a slowly expanding quasi-neutral cavity.
