Dust ion-acoustic shocks in quantum dusty pair-ion plasmas
Abstract The formation of dust ion-acoustic shocks (DIASs) in a four-component quantum plasma whose constituents are electrons, both positive and negative ions and immobile charged dust grains, is studied. The effects of both the dissipation due to kinematic viscosity and the dispersion caused by the charge separation as well as the quantum tunneling due to the Bohm potential are taken into acc...
متن کاملModulational instability of dust ion acoustic waves in astrophysical dusty plasmas with non thermal electrons
Propagation of dust ion acoustic waves in plasmas composed of nonthermal distributed electrons and stationary dust particles is investigated. Nonlinear Schrdinger equation is derived to describe small amplitude waves, using the reduction perturbation technique. Modulation instability of dust ion acoustic waves is analysed for this system. Parametric investigation indicates that growth rate of...
متن کاملDust-ion-acoustic supersolitons in dusty plasmas with nonthermal electrons.
Supersolitons are a recent addition to the literature on large-amplitude solitary waves in multispecies plasmas. They are distinguished from the usual solitons by their associated electric field profiles which are inherently distinct from traditional bipolar structures. In this paper, dust-ion-acoustic modes in a dusty plasma with stationary negative dust, cold fluid protons, and nonthermal ele...
متن کاملMagnetoplasmons in rotating dusty plasmas.
A rotating dusty plasma apparatus was constructed to provide the possibility of experimental emulation of extremely high magnetic fields by means of the Coriolis force, observable in a corotating measurement frame. We present collective excitation spectra for different rotation rates with a magnetic induction equivalent of up to 3200 T. We identify the onset of magnetoplasmon-equivalent mode di...
متن کاملPhase Transition in Dusty Plasmas:
We report on analytical and simulat n studies of mi ophy processes that trigger phase transitions in a dusty plasma subject to ion streaming. For res below the critica ure Pc for condensation, the grains acquire a large random kinetic energy and form a we upled fluid. P is increased to greater than Pc, the grains lose their kinetic energy and reach a strongly coupled crystal e state. The ust he...
