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…
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…
Effect of Ion Motion on Breaking of Longitudinal Relativistically Strong Plasma Waves: Khachatryan mode revisited
Ratan Kumar Bera, Arghya Mukherjee, Sudip Sengupta +1
Effect of ion motion on the spatio-temporal evolution of a relativistically strong space charge wave, is studied using a 1-D fluid simulation code. In our simulation, these waves a…
