Abstract
An investigation of the dust acoustic shock waves as well as solitary waves in an unmagnetized dusty plasma consisting of fluid of negatively charged dust grains, superthermal ions, and Maxwellian electrons under the influence of superthermally modified polarization force is presented. The polarization force is significantly influenced by superthermal ions. Reductive perturbation technique has been used to derive the Korteweg-de Vries-Burgers equation. It is illustrated that the superthermal polarization force significantly alters the characteristics of the negative polarity shock and solitary waves. It is also examined that the soliton energy gets depleted by the influence of superthermal polarization force.
