Dr. Punit Kumar
Associate Professor
Department of Physics
University of Lucknow
Lucknow - 226007, India
Research Profile
Engaged in research in theoretical Physics since 1995. Carried out extensive theoretical research on Free-Electron Lasers (FEL) and introduced ion-channel guiding. The investigations were performed in both the Low as well as in the High gain regimes. The results are being heavily cited.
Also worked in the field of Laser - Plasma Interaction and studied the parametric instabilities involved and explored possibilities of wakefield acceleration.
Currently, the focus of the research work is in the recently progressed area of Quantum Plasma. Have carried out studies on wakefield and ponderomotive acceleration in varied configurations. We have also worked on the parametric instabilities with special emphasis on modulation instability in magnetized quantum plasma. Studies on second harmonic Raman forward and backward scatterings have been performed and the results have been communicated for publication. Effect of dust in quantum plasma and particle acceleration by whistler waves have also been studied. Very recently, we have started studying laser interaction with magnetized quantum plasma taking into account the interaction between the spin-up and spin-down degenerate electrons. The difference in concentration induced by the magnetic field gives rise to a new wave.
Have recently started PIC simulation of gamma ray generation by intense laser beam interacting with highly dense plasma in collaboration with group headed by Prof. A. V. Kim at Institute of Applied Physics of the Russian Academy of Sciences, Russia.
