Coupling of neutrino beam-driven MHD waves and resonant instabilities in rotating magnetoplasmas with neutrino two-flavor oscillations
Jyoti Turi, Amar P. Misra
We present an analysis of neutrino-driven magnetohydrodynamic (MHD) waves and instabilities in a rotating magnetoplasma with weak neutrino interactions. We show that neutrino-drive…
Chaos in the dynamics of electromagnetic solitons in relativistic degenerate plasmas
S. Roy, S. Das Adhikary, A. P. Misra
We propose a coupled system for the nonlinear interaction between high-frequency, circularly polarized, intense electromagnetic (EM) waves and low-frequency electron-density pertur…
Pattern formation and spatiotemporal chaos in relativistic degenerate plasmas
S. Das Adhikary, A. P. Misra
We numerically study the nonlinear interactions of high-frequency circularly polarized electromagnetic (EM) waves and low-frequency electron-acoustic (EA) density perturbations dri…
Ion-beam driven dust-cyclotron and dust-lower-hybrid instabilities in nonthermal dusty magnetoplasmas with dust-charge fluctuation
A. P. Misra, N. P. Acharya, S. Basnet +1
We reveal a new dispersive dust-lower-hybrid (DLH)-like mode that can couple to modified dust-cyclotron (DC) waves in a dusty magnetoplasma by the influence of a streaming ion beam…
Dust-ion-acoustic solitons in an ion-beam-driven dusty magnetoplasma with adiabatic and nonadiabatic dust charge variations
N. P. Acharya, S. Basnet, A. P. Misra +1
We study the characteristics of small-amplitude nonlinear dust-ion-acoustic (DIA) solitary waves in active magnetized positive-ion-beam-driven dusty plasmas with the effects of non…
Coupling of Alfvén and magnetosonic waves in rotating Hall magnetoplasmas
A. P. Misra, R. Dey, V. Krishan
We study the linear theory of magnetohydrodynamic (MHD) waves, namely the Alfv{é}n and the fast and slow magnetosonic modes in a rotating Hall-MHD plasma with the effects of the o…
