Propagation and collisionless damping of topologically-protected surface plasma waves in non-uniformly magnetized plasma columns
Roopendra Singh Rajawat, Gennady Shvets
Recent theoretical studies revealed the existence of topologically-protected surface plasma waves (TSPWs) in cold magnetized plasmas assumed uniform along the direction of a uniaxi…
Effects of Laser Polarization on Target Focusing and Acceleration in a Laser-Ion Lens and Accelerator
Roopendra Singh Rajawat, Tianhong Wang, V. Khudik +1
We present the process of ion acceleration using ultra-thin foils irradiated by elliptically polarized, high-intensity laser pulses. Recently, efficient generation of monoenergetic…
Stationary Bernstein-Greene-Kruskal structures in a current carrying relativistic cold plasma
Roopendra Singh Rajawat, Sudip Sengupta, Nikhil Chakrabarti
Nonlinear stationary structures formed in a cold plasma with immobile ions in the presence of a relativistic electron current beam have been investigated analytically in the collis…
One dimensional PIC simulation of relativistic Buneman instability
Roopendra Singh Rajawat, Sudip Sengupta
Spatio-temporal evolution of the relativistic Buneman instability has been investigated in one dimension using an in-house developed particle-in-cell simulation code. Starting from…
