文摘We report here our recent studies of ultrastrong Langmuir iubulence by numerical simulation in two-fluid plasma.Many nonlinear phenomena,such as the formation and collapse of solitons,the onset of wavebreaking,the burnout and reborn of cavitons and so on,are observed in the simulation.Very intense cavitons(|E|^(2)/2coTa≈3 and δn/n0≈0.3) caused by relative weak pump0(|E|^(2)/2coTa≈0.05) and fluctuations (δnc/n0≈0.003) can exist in the system which are beyond the approximation of the Zakhorov model.
