I have derived a generalized dispersion relation including the ion contribution from the relativistic kinetic theory. The solution of the dispersion relation showed an enhanced instability growth rate due to the ion response. I also confirmed analytical results with two-dimensional PIC simulations, using the massively parallel and fully relativistic code OSIRIS using a realistic ion-to-electron mass ratio. The outcomes of my master thesis have been published in Journal of Plasma Physics (N. Shukla et al., the Journal of Plasma Physics 78, 81 (2012)). Show less

Activities and Societies: Generation of magnetic fields in plasmas at Faculty of Science and Technology, Department of Physics Umea Sweden I have examined several aspects of waves and instabilities in magnetized and un-magnetized plasmas. The work also included the study of the new and purely growing modes in quantum-plasmas. I have investigated a new kind of purely growing instability, which can spontaneously create magnetic fields due to the equilibrium polaritonic flows in an ultra-cold quantum electron–positron/hole plasma.This study can be of importance in the field of semiconductor physics as well as in astrophysical… Show more I have examined several aspects of waves and instabilities in magnetized and un-magnetized plasmas.

The research work has been published in various international journals. Show less
