Title: Relativistic dynamical bistability and adiabatic excitation of strong plasma waves

Abstract

Adiabatic evolution of the nonlinear resonantly driven dynamical system generic to a variety of plasma physics problems, including generation of large-amplitude plasma waves in a plasma beat-wave accelerator, is studied. The properties of the resonant Hamiltonian and the dynamics of its phase space for adiabatically varying parameters are considered. It is shown that the system can exhibit bistability and the Hamiltonian of a bistable system always follows the same trajectory for the adiabatically varying driver regardless of whether the system is excited or left quiescent. Descriptions of the bistability, autoresonance, and their possible combination based on the properties of the resonant Hamiltonian are given.

  • The nonlinear propagation of finite amplitude ion acoustic solitary waves in a plasma consisting of adiabatic warm ions, nonisothermal electrons, and a weakly relativistic electron beam is studied via a two-fluid model. A multiple scales technique is employed to investigate the nonlinear regime. The existence of the electron beam gives rise to four linear ion acoustic modes, which propagate at different phase speeds. The numerical analysis shows that the propagation speed of two of these modes may become complex-valued (i.e., waves cannot occur) under conditions which depend on values of the beam-to-background-electron density ratio {alpha}, the ion-to-free-electron temperature ratio {sigma},more » and the electron beam velocity v{sub 0}; the remaining two modes remain real in all cases. The basic set of fluid equations are reduced to a Schamel-type equation and a linear inhomogeneous equation for the first and second-order potential perturbations, respectively. Stationary solutions of the coupled equations are derived using a renormalization method. Higher-order nonlinearity is thus shown to modify the solitary wave amplitude and may also deform its shape, even possibly transforming a simple pulse into a W-type curve for one of the modes. The dependence of the excitation amplitude and of the higher-order nonlinearity potential correction on the parameters {alpha}, {sigma}, and v{sub 0} is numerically investigated.« less
  • Adiabatic evolution of a nonlinear resonantly driven dynamical system generic to a variety of plasma physics problems, including generation of large-amplitude plasma waves in a plasma heatwave accelerator, is studied. The corresponding Hamiltonian, depending on the strength and frequency of a slowly varying driver, has a variable number of fixed points and the dynamical system can be bi-stable due to repeated separatrix crossing in the phase space. It is shown that the Hamiltonian of a bi-stable system always follows the same trajectory for adiabatically varying driver regardless of whether the system is excited or left quiescent. The descriptions of themore » bi-stable and auto-resonant methods of excitation of a large plasma wake, based on the aforementioned properties of the bi-stable Hamiltonian, are given.« less
  • The parametric excitation of plasma oscillations in a relativistic plasma caused by oscillations in the electron mass in an external varying electric field is considered. The growth rates are obtained for plasma oscillations with T)very-much-greater-thanm$sub 0$c$sup 2$.
  • A nonlinear relativistic excitation of longitudinal electrostatic electron plasma wave at the beat frequency of two laser beams has been studied in a hot, collisionless, and homogeneous plasma. The nonlinearity has been taken through the ponderomotive force on electrons in the relativistic Vlasov equation. It is observed that the power conversion efficiency of the excited electron plasma wave is much higher for the relativistic calculation than that for the nonrelativistic calculations.
