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…
Interplay of single particle and collective response in molecular dynamics simulation of dusty plasma system
Srimanta Maity, Amita Das, Sandeep Kumar +1
Collective response of the plasma medium is well known and has been explored extensively in several contexts. The single particle response is typically treated as collisional inter…
Ion Vortex Beam
Chandrasekhar Shukla, Amita Das
Recent advances in intense short pulse laser interaction with thin foil enable us to accelerates the ions upto relativistic velocity in a controlled way. The accelerated ion beams…
Spiral waves in driven strongly coupled Yukawa systems
Sandeep Kumar, Amita Das
Spiral wave formations are ubiquitous in nature. In the present paper, the excitation of spiral waves in the context of driven two-dimensional dusty plasma (Yukawa system) has been…
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 (…
