Dissipative nonlinear waves in a gravitating quantum fluid Open
Nonlinear wave propagation is studied analytically in a dissipative, self-gravitating Bose Einstein condensate, in the framework of Gross-Pitaevskii model. The linear dispersion relation shows that the effect of dissipation is to suppress …

Comment on “Effects of damping solitary wave in a viscosity bounded plasma” [Phys. Plasmas <b>21</b>, 022118 (2014)] Open
Recently Gun Li et al. discussed “Effects of damping solitary wave in a viscosity bounded plasma” [Phys. Plasmas 21, 022118 (2014)]. The paper contains some serious errors which have been pointed out in this Comment.

Combined Effect of Magnetic Field and Compressibility on Rayleigh Taylor Instability Open
The nonlinear analysis of the combined effect of magnetic field and compressibility on the growth rate of Rayleigh-Taylor (RT) instability has been investigated for inviscid two fluid interface. We have considered an interface-parallel den…

Shock Induced Symmetric Compression in a Spherical Target Open
Shock induced symmetric compression has been studied in a spherical target. The shock induced interfacial radius will shrink and would reach a minimum point during implosion situation. However, after implosion the plasma tries to expand in…
