Doctoral Research

My doctoral thesis work focuses on the study of collective phenomena in a large volume dusty plasma medium, which is important for the understanding of astrophysical plasma phenomena, complex fluid flow, transport and trapping of particles in processing plasmas etc. I had specifically concentrated on the collective dynamics of dusty plasma and its characteristics with an external potential perturbation, transport and trapping of dust particles in the inductively coupled diffused plasma, and evolution of certain instabilities such as dissipative, ion-streaming, and dust acoustic etc in the large volume dusty plasma, which give rise to waves and co-rotating vortices. Meanwhile, the excitation of collective modes (solitary electron hole) and relaxation dynamics of low temperature plasma were also topics of focus during the PhD period. For studying the mentioned topics, different gas discharge (filament discharge, dc discharge, and inductively coupled discharge) and data analysis techniques were used.
