Modulational instability of dust ion acoustic waves in astrophysical dusty plasmas with non thermal electrons

  Propagation of dust ion acoustic waves in plasmas composed of nonthermal distributed electrons and stationary dust particles is investigated. Nonlinear Schrdinger equation is derived to describe small amplitude waves, using the reduction perturbation technique. Modulation instability of dust ion acoustic waves is analysed for this system. Parametric investigation indicates that growth rate of...

Localization of intense electromagnetic waves in plasmas.

We present theoretical and numerical studies of the interaction between relativistically intense laser light and a two-temperature plasma consisting of one relativistically hot and one cold component of electrons. Such plasmas are frequently encountered in intense laser-plasma experiments where collisionless heating via Raman instabilities leads to a high-energetic tail in the electron distribu...

Molecular dynamics simulations of plasmas in electromagnetic fields: collisional absorption

Collisional absorption of dense fully ionized plasmas in strong laser fields has been investigated using molecular dynamics simulations [1, 2, 3]. The external electric field was implemented as a homogeneous linearly polarized harmonic field. The main difficulty in order to simulate a fully ionized plasma is to model the attractive electron–ion interaction: the pure Coulomb potential has a sing...

Hydrodynamics, magnetohydrodynamics, and astrophysical plasmas

1 Introduction It is not uncommon to encounter the assertion that the dynamical evolution of the large-scale bulk velocity v of a collisionless gas is not described by the hydrodynamic (HD) equations. A favorite " reason " is the statement that pressure cannot be defined in the absence of collisions. Then in some quarters it is believed that the large-scale bulk dynamics of a swirling magnetize...

Absorption of electromagnetic and gravitational waves by Kerr black holes

Article history: Received 29 August 2017 Accepted 17 September 2017 Available online 25 September 2017 Editor: M. Trodden We calculate the absorption cross section for planar waves incident upon Kerr black holes, and present a unified picture for scalar, electromagnetic and gravitational waves. We highlight the spin-helicity effect that arises from a coupling between the rotation of the black h...
