Arbitrary amplitude ion acoustic solitary structures in a collisionless magnetized plasma consisting of nonthermal and isothermal electrons
Sandip Dalui, Sankirtan Sardar, Anup Bandyopadhyay
We have used the Sagdeev pseudo-potential technique to investigate the arbitrary amplitude ion acoustic solitons, double layers and supersolitons in a collisionless magnetized plas…

Existence and stability of dust ion acoustic double layers described by the combined MKP-KP equation
Sankirtan Sardar, Anup Bandyopadhyay, K. P. Das
The purpose of this paper is to expand the recent work of Sardar et al. [Phys. Plasmas 23, 123706 (2016)] on the existence and stability of alternative dust ion acoustic solitary w…

Higher order stability of dust ion acoustic solitary wave solution described by the KP equation in a collisionless unmagnetized nonthermal plasma in presence of isothermal positrons
Sankirtan Sardar, Anup Bandyopadhyay, K. P. Das
Sardar et al. [Phys. Plasmas 23, 073703 (2016)] have studied the stability of small amplitude dust ion acoustic solitary waves in a collisionless unmagnetized electron - positron -…
