We have studied the formation of relativistic solitary waves due to nonlinearinteraction of strong electromagnetic wave with the plasma wave. Here, our plasma isrelativistic both in temperature and in streaming speed. A set of equations consisting ofscalar and vector potentials together with a third order equation for the enthalpy inphoton gas plasma is obtained analytic...

We discuss some aspects of interactions of high-frequency electromagnetic waves with plasmas, assuming that the intensity of radiation is sufficiently large, so that the photon-photon interaction is more likely than the photon-plasma particle interaction. In the stationary limit, solving the kinetic equation of the photon gas, we derive a distribution function. With this distribution function a...

Possibility of establishment of equilibrium between the photon and the dense photon bunch is studied. In the case, when the density of plasma does not change, the condition of production of the Bose-Einstein condensate is obtained. It is shown that the inhomogeneity of density of photons leads to a new intermediate state of the photon gas. 52.25.Os, 52.27.Ny, 52.40.Db Typeset using REVTEX 1 Imp...

A new mechanism for generating coherent radiation from a laser-ionized gas-filled capacitor array is presented. This scheme directly converts a static electric field of wave number k0 into coherent radiation pulses. The physical mechanism is analogous to photon acceleration in plasma waves, and in this sense, photons are accelerated from zero frequency (zero energy) to a frequency ωp2/2k0c. The...

The recent status of hard thermal photon production in relativistic heavy ion collisions is reviewed and the current rates are presented with emphasis on corrected bremsstrahlung processes in the quark-gluon plasma (QGP) and quark-hadron duality. Employing Bjorken hydrodynamics with an EOS supporting the phase transition from QGP to hot hadron gas (HHG), thermal photon spectra are computed. For...

abstract in this work, the dry reforming of methane was studied using a corona and glow discharge plasma microreactors. a chemical kinetic model was developed to understand the reaction better. the modelization allowed prediction of the reactants conversion according to the energy transfer to the gas (p×τ). the β value is trait of the energy cost, whatever this value was leeser indicated better...

the experimental studies of methane conversion to higher hydrocarbons and methanol using a dielectric barrier discharge (dbd) reactor are presented in this article. the process is carried out at ambient atmospheric pressure and temperature. the dbd reactor is stimulated by an alternative voltage of 50 hz and amplitude of max.23kv. the examination of the effect of voltage and flow rates on metha...

Visible imaging of gas puffs has been used on the Alcator C-Mod tokamak to characterize edge plasma turbulence, yielding data that can be compared with plasma turbulence codes. Simulations of these experiments with the DEGAS 2 Monte Carlo neutral transport code have been carried out to explore the relationship between the plasma fluctuations and the observed light emission. By imposing two-dime...
