One-dimensional full particle simulations of almost perpendicular supercritical collisionless shocks over a wide AlfvÃ©n Mach number range are presented. The physical ion to electron mass ratio has been used; however, due to computer time limitations a value of the ratio of the electron plasma...

Stimulated Raman scattering, stimulated Raman cascade, and the transition from Raman cascade into photon condensation, induced by linearly polarized intense laser interacting with an underdense uniform collisionless plasma, are studied by particle simulations. In addition to the stimulated Raman...

Collisionless forced magnetic reconnection in an electron-positron plasma, where the mechanism of the magnetic field breaking is inertia of plasma particles, is considered. The model under analytical investigation is the so-called Taylor problem: a tearing stable slab plasma equilibrium with a...

Nonlinear propagation of a circularly polarized intense short-pulse laser through a plasma, immersed in a strong axial magnetic field, is examined. The relativistic mass effect makes the group velocity of the laser intensity-dependent. Different portions of the laser pulse travel with different...

The amplitude modulation of quantum ion-acoustic waves (QIAWs) along an external magnetic field is studied in a quantum electron-positron-ion (e-p-i) magnetoplasma. Reductive perturbation technique is used to derive the three-dimensional nonlinear SchrÃ¶dinger equation which governs the slow...

Frequency sum rules are derived in extended quantum systems of nonrelativistic fermions from a minimal set of assumptions on dynamics in infinite volume, for ground and thermal states invariant under space translations or a lattice subgroup. For the jellium Coulomb model, they imply the one...

The one-dimensional oblique propagation of large amplitude magnetohydrodynamic (MHD) waves in a high-Î² quantum Hall-MHD plasma is studied with electron spin-1/2 effects. The plasma Î² becomes high by the condition for the nonrelativistic fluid model to be valid and the condition for the...

This paper presents a derivation of the phase-matching conditions for generation of the third-harmonic (3Ï‰1) and combination frequencies (Ï‰1+2Ï‰2), by two fundamental electromagnetic waves of frequencies Ï‰1 and Ï‰2, propagating in the extraordinary mode along a magnetic field...

The motion of charged particles in a linearly polarized EH-ubitron field with sinusoidal time dependence of the variable component of the magnetic field is investigated. It is shown that, depending on the parameters of the system and the initial conditions of entry of the particle into the...
