An experiment has been performed to study the behavior of dust acoustic waves driven at high frequencies f 100 Hz , extending the range of previous work. In this study, two previously unreported phenomena are observed—interference effects between naturally excited dust acoustic waves and driven dust acoustic waves, and the observation of finite dust temperature effects on the dispersion relatio...

The omnipresence of dust particulates in space and astrophysical plasmas has been attracting numerous researchers to study the collective excitation propagation dynamics different eigen-mode structures diversifed astrocosmic circumstances for years. It includes planetary rings, interplanetary space, cometary tails, asteroid zones, atmospheres, etc. ubiquitous charged possess degrees dynamic fre...

Electrostatic dust-acoustic shock waves are investigated in a viscous, complex plasma consisting of dust particles, electrons, and ions. The system is modelled using the generalized hydrodynamic equations, with strong coupling between the dust particles being accounted for by employing the effective electrostatic temperature approach. Using a reductive perturbation method, it is demonstrated th...

Dusty plasmas are known to support a diverse range of instabilities, including both generalizations standard plasma instabilities and ones caused by effects specific dusty systems. It has been recently demonstrated that novel broad class streaming termed resonant drag (RDIs), can be attributed particular resonance phenomenon, manifested defective eigenvalues the linearized dust/fluid system. In...

The multi-species plasma of natural or laboratory origin is often considered to host nonlinear ion-acoustic waves. We present calculations ion fluxes induced by waves in a consisting multiple populations, electrons, and dust. following models are considered: an electron-ion with cold ions, bi-ion two types warm positively charged dusty plasma. It found that the plasma, wave-induced flux directe...

Abstract We study asymptotic reductions and solitary waves of a weakly nonlocal defocusing nonlinear Schrödinger (NLS) model. The hydrodynamic form the latter is analyzed by means multiscale expansion methods. To leading-order approximation (where only first moments response function present), we show that waves, in dark solitons, are governed an effective Boussinesq/Benney–Luke (BBL) equation,...
