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…
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…
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…
Observation of enhanced absorption of laser radiation by nano structured targets in PIC simulations
Chandrasekhar Shukla, Amita Das
It is well known that Brunel's vacuum heating mechanism is operative for laser energy absorption when the target plasma density rises sharply. For non-relativistic laser intensitie…
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…
