The pseudopotential approach is used to investigate the ion thermal and electron superthermal effects on slow mode solitary wave propagation characteristics in a negative plasma, comprising warm positive ions kappa-distributed electrons. Sagdeev for plasma model derived analyzed systematic way. While it well known that supports of fast normal solitons, found supports, addition supersolitons dou...

The presence of dynamic, large amplitude solitary waves in the auroral regions of space is well known. Since their velocities are of the order of the ion acoustic speed, they may well be considered as being generated from the nonlinear evolution of ion acoustic waves. However, they do not show the expected width-amplitude correlation for K-dV solitons. Recent POLAR observations have actually re...

Large amplitude parallel propagating electric field structures of nonlinear electron-acoustic waves are examined in an unmagnetized magnetosheath plasma. Based on the observations and simulations by Ergun et al. (2016), plasma side ion diffusion layer is modeled a 3-component adiabatic fluid dynamic consisting cold magnetospheric (MSP) electrons, background ions. Using Sagdeev pseudopotential t...

A frequency-averaged quasilinear model is derived and experimentally validated for the evolution of ion acoustic turbulence (IAT) along the centerline of a 100-A class, LaB_{6} hollow cathode. Probe-based diagnostics and a laser induced fluorescence system are employed to measure the properties of both the turbulence and the background plasma parameters as they vary spatially in the cathode plu...

A direct numerical simulation of a strong relativistic collisionless shock propagating into an unmagnetized medium has been performed in two spatial dimensions. It is found that: (i) collisionless shock exists, (ii) particle acceleration is insignificant, (iii) the shock does not generate “quasi-static” magnetic fields, contrary to recent claims by other authors. All our results agree with a si...

An analytical theory of wave turbulence is developed for pure compressible magnetohydrodynamics in the small $\beta$ limit. In contrast to previous works where multiple scale method was not mentioned and slow magneto-acoustic waves were included, I present here a fast only which an asymptotic closure possible three dimensions. introduce Elsasser fields (canonical variables) show their linear re...

An empirical potential energy surface has been developed for the Ne·OH/D complexes from the experimentally observed vibrational and rotational energy levels with ab initio calculations being used for initial esti-

to investigate the electromagnetic interaction of molecules inside the nanotubes, first, the structure of nanotubes b16n16 was optimized with hybrid density functional theory (b3lyp) using the epr-ii basis set, then cu, cu+, cu++ were located in nanotube and we studied the total energy, band gap energy, electrical potential, changes of band gap energy in terms of total energy and dipole moment ...
