Novel features of non-linear Raman instability in a laser plasma

The electron phase space evolution in a non-relativistic and homogeneous laser of stimulated Raman scattering is investigated by a numerical simulation. The mechanism of electron acceleration in the potential wells of the plasma wav...

Kinetics of the Raman scattering in a laser corona using a transform method

in a strongly non-linear regime. The method is stabilized by a simplified Fokker–Planck of equations in a one-dimensional geometry to describe the Raman backscattering) on the instability development and their com...

Numerical simulation of wave-particle interaction in laser plasmas

modeltaking into account also non-linear effects of wave-particle interaction. We discuss Raman scattering, which can give a birth to a strong backscattered electromagnetic of such instability employing a simple e...

New approach to instability in non-linear circuits and systems

The contribution is mainly concerned with presentation of a new fundamental approach to structural properties of linear and non-linear causal system representations. It has been proven that complete analysis of instabil...

Reduced problem of non-linear aeroelastic stability and relevant post-critical states

This paper deals with the development of a uniform theory based simultaneously on theory and experiments which would cover known cases of aeroelastic instability and restabilisation due to non-linear and non-symmet...

Kinetics of Raman instability in laser plasma

The phase-space evolution in a non-relativistic and homogeneous laser plasma in the presence of the stimulated Raman scattering is studied using the Fourier-Hermite transform method applied to the Vlasov equation in a 1D model. Nume...

Electron kinetics in a laser plasma with increased collisionality

The fast electron group may be generated by various accelerating mechanisms. One of the key processes leading to the electron acceleration is the Raman scattering in its non-linear phase. The development of the Raman

On hydromagnetic instabilities and the mean electromotive force in a non-uniformly stratified Earth?s core affected by viscosity

Linear magnetoconvection in a model of a non-uniformly stratified horizontal rotating fluid layer with a toroidal magnetic field is investigated for no-slip and finitely electrically conductive boundaries and with very thin stably s...
