Evidence of new finite beam plasma instability for magnetic field generation
Amita Das, Atul Kumar, Chandrasekhar Shukla +8
We demonstrate by computer simulations, laser plasma experiments, and analytic theory that a hitherto unknown instability is excited in the beam plasma system with finite transvers…
Observation of 1-D time dependent non-propagating laser plasma structures using Fluid and PIC codes
Deepa Verma, Ratan Kumar Bera, Atul Kumar +2
The manuscript reports the observation of time dependent localized and non-propagating structures in the coupled laser plasma system through 1-D fluid and PIC simulations. It is re…
Energy principle for 2D electromagnetic, relativistic, interpenetrating, counter streaming plasma flows
Atul Kumar, Predhiman Kaw, Amita Das
A relativistic electron beam propagating through plasma induces a return current in the system. Such a system of counterstreaming forward and return current is susceptible to host…
