  • Dust-Alfvenic Shocklets in Dusty Plasmas 
    Shukla, P. K; Morfill, G. E; Krishan, V (IOP Publishing, 2004)
    We show that the Hall dust magnetohydrodynamic equations admit a non-stationary dust-Alfvénic shock solution in dusty plasmas. The dust-Alfvénic shocklet (DAS) occurs on a long temporal (dust gyroperiod) and spatial (dust ...
  • Electrostatic oscillations in the presence of grain-charge perturbations in dusty plasmas 
    Varma, R. K; Shukla, P. K; Krishan, V (The American Physical Society, 1993-05)
    The properties of electrostatic oscillations and instability phenomena are studied, accounting for the time-dependent variation of the grain electric charge due to wave motions in an unmagnetized dusty plasma. It is found ...
  • The modulation of radiation in an electron-positron plasma 
    Gangadhara, R. T; Krishan, V; Shukla, P. K (Royal Astronomical Society, 1993-05-01)
    The modulational instability of a large-amplitude, linearly polarized electromagnetic wave propagating in an electron-positron plasma is considered, including the combined effect of relativistic mass variation of the plasma ...
