Weibel instability beyond bi-Maxwellian anisotropy
Thales Silva, Bedros Afeyan, Luis O. Silva
The shape of the anisotropic velocity distribution function, beyond the realm of strict Maxwellians can play a significant role in determining the evolution of the Weibel instabili…
Simulations of Kinetic Electrostatic Electron Nonlinear (KEEN) Waves with Variable Velocity Resolution Grids and High-Order Time-Splitting
Bedros Afeyan, Fernando Casas, Nicolas Crouseilles +4
KEEN waves are nonlinear, non-stationary, self-organized asymptotic states in Vlasov plasmas outside the scope or purview of linear theory constructs such as electron plasma waves…
Control of Stimulated Raman Scattering in the Strongly Nonlinear and Kinetic Regime Using Spike Trains of Uneven Duration and Delay: STUD Pulses
B. J. Albright, L. Yin, B. Afeyan
Stimulated Raman scattering (SRS) in its strongly nonlinear, kinetic regime is controlled by a technique of deterministic, strong temporal modulation and spatial scrambling of lase…
Optimal Control of Laser-Plasma Instabilities Using Spike Trains of Uneven Duration and Delay: STUD Pulses
Bedros Afeyan, Stefan Hüller
Adaptive methods of laser irradiation of plasmas are proposed consisting of deterministic, `on-off' amplitude modulations in time, and intermittently changing speckle-patterns. The…
Vlasov on GPU (VOG Project)
M. Mehrenberger, C. Steiner, L. Marradi +3
This work concerns the numerical simulation of the Vlasov-Poisson set of equations using semi- Lagrangian methods on Graphical Processing Units (GPU). To accomplish this goal, modi…
Wavelets, Curvelets and Multiresolution Analysis Techniques in Fast Z Pinch Research
Bedros Afeyan, Kirk Won, Jean Luc Starck +1
Z pinches produce an X ray rich plasma environment where backlighting imaging of imploding targets can be quite challenging to analyze. What is required is a detailed understanding…
