Relativistic Klein-Gordon-Maxwell multistream model for quantum plasmas
F. Haas, B. Eliasson, P. K. Shukla
A multistream model for spinless electrons in a relativistic quantum plasma is introduced by means of a suitable fluid-like version of the Klein-Gordon-Maxwell system. The one and…
Nonlinear dynamics of large amplitude dust acoustic shocks and solitary pulses in dusty plasmas
P. K. Shukla, B. Eliasson
We present a fully nonlinear theory for dust acoustic (DA) shocks and DA solitary pulses in a strongly coupled dusty plasma, which have been recently observed experimentally by Hei…
Relativistic X-Ray Free Electron Lasers in the Quantum Regime
Bengt Eliasson, Padma Kant Shukla
We present a nonlinear theory for relativistic X-ray free electron lasers in the quantum regime, using a collective Klein-Gordon (KG) equation (for relativistic electrons), which i…
Novel Attractive Force Between Ions in Quantum Plasmas
Padma Kant Shukla, Bengt Eliasson
We report new attractive force between ions that are shielded by degenerate electrons in quantum plasmas. Specifically, we show that the electric potential around an isolated ion h…
Nonlinear propagation of light in Dirac matter
Bengt Eliasson, Padma K. Shukla
The nonlinear interaction between intense laser light and a quantum plasma is modeled by a collective Dirac equation coupled with the Maxwell equations. The model is used to study…
Modulational instability and nonlinear evolution of two-dimensional electrostatic wave packets in ultra-relativistic degenerate dense plasmas
A. P. Misra, P. K. Shukla
We consider the nonlinear propagation of electrostatic wave packets in an ultra-relativistic (UR) degenerate dense electron-ion plasma, whose dynamics is governed by the nonlocal t…
Relativistic Laser-Plasma Interactions in the Quantum Regime
Bengt Eliasson, Padma K. Shukla
We investigate the nonlinear interaction between a relativistically strong laser beam and a plasma in the quantum regime. The collective behavior of the electrons is modeled by a K…
Localized whistlers in magnetized spin quantum plasmas
A. P. Misra, G. Brodin, M. Marklund +1
The nonlinear propagation of electromagnetic (EM) electron-cyclotron waves (whistlers) along an external magnetic field, and their modulation by electrostatic small but finite ampl…
Numerical study of the magnetic electron drift vortex mode turbulence in a nonuniform magnetoplasma
Dastgeer Shaikh, B Eliasson, P K Shukla
A simulation study of the magnetic electron drift vortex (MEDV) mode turbulence in a magnetoplasma in the presence of inhomogeneities in the plasma temperature and density, as well…
3D Electron Fluid Turbulence at Nanoscales in Dense Plasmas
Dastgeer Shaikh, P. K. Shukla
We have performed three dimensional nonlinear fluid simulations of electron fluid turbulence at nanoscales in an unmagnetized warm dense plasma in which mode coupling between wave…
Nonlinear Saturation of the Weibel Instability in a Dense Fermi Plasma
F. Haas, P. K. Shukla, B. Eliasson
We present an investigation for the generation of intense magnetic fields in dense plasmas with an anisotropic electron Fermi-Dirac distribution. For this purpose, we use a new lin…
Weibel Instabilities in Dense Quantum Plasmas
Levan N. Tsintsadze, P. K. Shukla
The quantum effect on the Weibel instability in an unmagnetized plasma is presented. Our analysis shows that the quantum effect tends to stabilize the Weibel instability in the hyd…
Magnetosonic solitons in a Fermionic quantum plasma
M. Marklund, B. Eliasson, P. K. Shukla
Starting from the governing equations for a quantum magnetoplasma including the quantum Bohm potential and electron spin-1/2 effects, we show that the system of quantum magnetohydr…
Nonlinear interactions between kinetic Alfvén and ion-sound waves
G. Brodin, L. Stenflo, P. K. Shukla
The resonant interaction between kinetic Alfvén and ion-acoustic waves is considered using the Hall-MHD theory. The results of previous authors are generalized to cover both finite…
Stabilisation of BGK modes by relativistic effects

We investigate the acceleration of electrons via their interaction with electrostatic waves, driven by the relativistic Buneman instability, in a system dominated by counter-propag…
Modulated dust-acoustic wave packets in a plasma with non-isothermal electrons and ions
Ioannis Kourakis, P. K. Shukla
Nonlinear self-modulation of the dust acoustic waves is studied, in the presence of non-thermal (non-Maxwellian) ion and electron populations. By employing a multiple scale techniq…
Lagrangean formulation of ion- and dust-ion-acoustic waves
Ioannis Kourakis, Padma Kant Shukla
Ion-acoustic modes propagating in unmagnetized dusty plasmas are studied by applying a generic collisionless fluid model. An Eulerian-to-Lagrangean variable transformation leads to…
