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…
Merger and reconnection of Weibel separated relativistic electron beam
Chandrasekhar Shukla, Atul Kumar, Amita Das +1
The relativistic electron beam (REB) propagation in a plasma is fraught with beam plasma instabilities. The prominent amongst them being the collisionless Weibel destabilization wh…
Spiral Waves in Driven Dusty Plasma Medium: Generalized Hydrodynamic Fluid Description
Sandeep Kumar, Bhavesh Patel, Amita Das
Spiral waves are observed in many natural phenomena. They have been extensively represented by the mathematical FitzHugh-Nagumo (FHN) model [Barkley et al., Phys. Rev. A 42, 2489 (…
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…
Magnetic field generation in finite beam plasma system
Amita Das, Atul Kumar, Chandrasekhar Shukla +7
For finite systems boundaries can introduce remarkable novel features. A well known example is the Casimir effect [1, 2] that is observed in quantum electrodynamic systems. In clas…
