Nonlinear Landau Collisions Without Collision Tensors
R. Jorge, B. Herfray, C. Vega +1
Far-from-equilibrium plasmas require nonlinear Coulomb collisions, but direct three-dimensional Hermite discretization of the Landau operator needs an impractical dense tensor. By…

Direct Microstability Optimization of Stellarator Devices
R. Jorge, W. Dorland, P. Kim +4
Turbulent transport is regarded as one of the key issues in magnetic confinement nuclear fusion, both for tokamaks in stellarators. In this work, we show that a significant decreas…
