Soliton phenomena in electron beam plasma
Abstract
As a model equation for an electron beam plasma system, the unstable nonlinear Schrodinger (UNS) equation, iq sub x plus q sub tt plus 2/q/(2)q equals 0, is proposed. Recent works on this equation are reported. The UNS equation is a canonical equation which describes nonlinear modulations of wave amplitude in unstable media. In the electron beam plasma system, near the critical wave number, the wave amplitude obeys the UNS equation. Results derived by investigating this equation show that solitons can be caused in the system. In addition, the role of solitons in unstable media is clarified.
