1-D particle-in-cell simulations of electron acoustic solitary structures in an electron beam-plasma

Electrostatic solitary (ES) structures have been frequently observed in the solar wind, Earth’s and other planetary magnetosphere and are the most widely theoretically studied waves in literature. However, there are very few studies in which simulations and theoretical studies have been performed si...
