Numerical heating in particle-in-cell simulations with Monte Carlo binary collisions
E. Paulo Alves, Warren B. Mori, Frederico Fiuza
The binary Monte Carlo (MC) collision algorithm is a standard and robust method to include binary Coulomb collision effects in particle-in-cell (PIC) simulations of plasmas. Here,…
Data-driven discovery of reduced plasma physics models from fully-kinetic simulations
E. Paulo Alves, Frederico Fiuza
At the core of some of the most important problems in plasma physics -- from controlled nuclear fusion to the acceleration of cosmic rays -- is the challenge to describe nonlinear,…
Nonthermal ion acceleration by the kink instability in nonrelativistic jets
E. Paulo Alves, Jonathan Zrake, Frederico Fiuza
We investigate the self-consistent particle acceleration physics associated with the development of the kink instability (KI) in nonrelativistic, electron-ion plasma jets. Using 3D…
Formation of collisionless shocks in magnetized plasma interaction with kinetic-scale obstacles
F. Cruz, E. P. Alves, R. A. Bamford +3
We investigate the formation of collisionless magnetized shocks triggered by the interaction between magnetized plasma flows and miniature-sized (order of plasma kinetic-scales) ma…
Essential criteria for efficient pulse amplification via Raman and Brillouin scattering
R. M. G. M. Trines, E. P. Alves, E. Webb +14
Raman and Brillouin amplification are two schemes for amplifying and compressing short laser pulses in plasma. Analytical models have already been derived for both schemes, but the…
High orbital angular momentum harmonic generation
J. Vieira, R. M. G. M. Trines, E. P. Alves +5
We identify and explore a high orbital angular momentum (OAM) harmonics generation and amplification mechanism that manipulates the OAM independently of any other laser property, b…
