Research Interests

My research interests include:
# Plasma Physics
My current research interests are located in the fields of Theoretical Plasma Physics, with emphasis on Nonlinear Dynamics, Waves and Instabilities in Classical and Quantum Plasmas, and Plasmonics.
The main focus points are summarized in the following:
# Linear and Nonlinear Waves Propagating in Plasmas:
• Nonlinear excitations: solitons, double layers (shocks), blowup/explosive, Rogue Waves, vortices, modulated envelope wave packets, instabilities, ponderomotive coupling effects.
• Electrostatic and electromagnetic excitations in: pair-ion plasma, electron-positron-ion plasmas, two-electron temperature plasma, two-ion temperature plasma, nonthermal plasma.
• Beam-plasma interactions: beam-plasma properties, pulse propagation and instabilities.
• Surface waves (surface plasmon-polaritons): electrostatic and electromagnetic excitations, ponderomotive coupling effect, envelope solitons, and counterstreaming plasmas.
• Wake potential: test charge properties in multi-component plasma.
# Dusty Plasmas (Complex plasmas):
• Basic properties: charging effect, dispersion properties, external magnetic field, two-ion temperature, ion beam, ion streaming, and dust-size distribution.
• Electrostatic excitations: dust-acoustic solitary waves, dust-ion-acoustic solitary waves and shocks, instabilities.
• Electromagnetic excitations: self-gravitational, rotational, opposite polarity dust particles, instabilities.
• Charging of dust grains: ionization source model.
# Nonlinear Wave Phenomena (Soliton Theory)
Nonlinear wave phenomena (Soliton Theory). Together with strange attractors and chaos, solitons play a key role in nonlinear science. Solitons are stable, particle-like, nonlinear pulses which result from a critical balance between nonlinearity and dispersion (or dissipation). My theoretical work is concerned with partial differential equations (PDEs) that admit, specifically, soliton solutions and in general travelling wave solutions. Such PDEs model shallow- and deep-water waves, charge-density waves in plasmas, nonlinear optical pulses, nonlinear transmission lines, fluxons in Josephson transmission lines, nerve pulses, waves in the atmosphere, Bose-Einestein condensates, etc. Also, I am interested in integrability tests and painlevé analysis of PDEs.
Powerful symbolic manipulation programs such as Mathematica, Macsyma, Reduce, Maple, and Derive offer virtually unlimited potential to do mathematics on a computer. The symbolic-crunching capabilities of these software packages (Mathematica and Maple) allow me to obtain soliton solutions without having to do the tedious algebra and calculus with pen and paper.
# Lie Groups and Symmetry Reduction Techniques
Lie symmetry analysis and the application of Lie groups to nonlinear differential equations arising in mathematical physics. Within the area of symmetry analysis, I am interested in both classical and nonclassical point symmetries, as well as in nonlocal (potential) symmetries. I am most interested in the general class of nonlinear diffusion-convection equations, which has a variety of applications to the real physical world such as plasma physics, metallurgy, segregation of granular materials, porous media ( including unsaturated flow), and migration of nuclides leaching out of a repository, to name only a few.
