Particle acceleration at magnetized, relativistic, turbulent shock fronts
Physical Review Research, 2023 The efficiency of particle acceleration at shock waves in relativistic, magnetized astrophysical outflows is a debated topic with far-reaching implications. Here, we study the impact of well-developed turbulence in the pre-shock plasma.

Relativistic self focusing and frequency shift of super-Gaussian laser beam in plasma
Results in Physics, 2020 Relativistic self focusing and frequency shift of laser beam having super-Gaussian profile in space and Gaussian profile in time is studied in a plasma. The relativistic mass nonlinearity is found to cause time dependent self focusing of the laser pulse ...

Discussion on Rayleigh equation obtained for a Hall thruster plasma with dust
Journal of Theoretical and Applied Physics, 2018 The present study focuses on the Rayleigh equation derived in the case of a Hall thruster plasma having dust contamination, produced near the exit of the channel due to the finite divergence of the accelerated ions and the sputtering of the walls. In the

Particle acceleration by twisted laser beams
Frontiers in Physics, 2022 We consider particle acceleration in plasmas, using twisted laser beams, or beams with orbital angular momentum. We discuss different acceleration processes using two LG laser modes, which include donut wakefield, beat-wave and self-torque acceleration ...
