The dust-acoustic shock waves have been theoretically investigated using reductive perturbation technique. An unmagnetized four-component dusty plasma system consisting of nonextensive q-distributed electrons, Boltzmann distributed ions, and negatively as well as positively charged dust particles has been considered. The solution of Burgers equation in planar geometry is numerically analyzed. I...

The characteristics of arbitrary amplitude dust ion acoustic solitary waves (DIASWs) are studied in unmagnetized dusty plasmas whose constituents are cold uid ions, nonextensive electrons and stationary negative/positive dust particles. The pseudopotential approach has been used to investigate the structure of localized waves. It is found that, solitary waves exist in a definite interval for th...

Abstract The small amplitude ion-acoustic solitary waves in the magneto-rotating plasma consisting of cold fluid ions, hot positrons, and two-temperature electrons (cold electrons) are investigated when obey a modified Cairns-Tsallis distribution. By using reductive perturbation method, we derive Korteweg–de Vries equation obtain wave solutions. dependences solutions on nonextensive q -paramete...

Conditions of to exist Numerical analyses for depend on nonextensive and nonthermal parameters made. We study ion consisting cold inertial ions, positrons, hot (two-temperature) electrons, where electrons positrons a have different parameters. Base hydrodynamic equations Sagdeev pseu...

Sheath formation and its characteristics are studied in collisional magnetized plasma consisting of nonextensive electrons thermal ions. Using two-fluid model, the Bohm criterion for ion velocity is deduced as a function parameters shown that ion-neutral collisions impose an upper limit criterion. It also found deviation from standard Maxwellian distribution significantly affects sheath charact...

We investigate perturbative thermodynamic geometry of nonextensive ideal classical, Bose, and Fermi gases. We show that the intrinsic statistical interaction of nonextensive Bose (Fermi) gas is attractive (repulsive) similar to the extensive case but the value of thermodynamic curvature is changed by a nonextensive parameter. In contrary to the extensive ideal classical gas, the nonextensive on...
