Magnetosonic Shocks And Solitons In Fermi Plasma With Quasiperiodic Perturbation (2022)
Published in: IEEE Transactions on Plasma Science ( Volume: 50, Issue: 6)
In this article, we consider a dense stellar plasma consisting of predominantly electrons, positrons, and ions under the action of the magnetic field of the star. We derived the Korteweg–de Vries Burgers (KdV-Burgers) equations by using the reductive perturbation technique and obtained shock and solitary profiles for magnetoacoustics waves. We further studied the self-interaction of such stationary formations and the amplitude-modulated envelope solitons. The possibility of a rogue wave-like structure is also discussed. The results will be helpful to interpret magnetoacoustics wave formations in solar corona or other stellar entities and can help in the study of inhomogeneous plasmas in laboratory and fusion reactors.
Propagation of Rogue Waves and Cnoidal Waves Formations through Low Frequency Plasma Oscillations (2020)
Published in: African Review of Physics, Vol. 15 (2020)
In this paper, we consider the propagation of electron acoustic solitary waves in semi-classical plasma. Using the quantum hydrodynamic model we obtain the dispersion relation and study the parametric variations of the dispersion curve. We further study the solitary profiles and their evolution by using the Korteweg-de Vries Burger equation. We extended our work to the study of Rogue waves. The results provide interesting findings that have laboratory and astrophysical importance.
