Variational Formulation of a Hybrid Kinetic and Gyrokinetic Model for Astrophysical and Laboratory Plasmas
F. N. deOliveira-Lopes, S. C. Thatikonda, D. Told +5
The paper introduces a Lagrangian model that couples fully kinetic ions with gyrokinetic electrons to efficiently simulate solar‑wind electromagnetic turbulence, using variational…
Plasmoid formation via competing lower-hybrid drift and Kelvin-Helmholtz instabilities: A hybrid kinetic-gyrokinetic simulation study
S. Thatikonda, F. N. De Oliveira-Lopes, A. Mustonen +3
We investigate the nonlinear formation of plasmoids in 2D low-beta current sheets through the interplay between the Kelvin-Helmholtz instability (KHI) and the lower-hybrid drift in…
Verification of a hybrid gyrokinetic model using the advanced semi-Lagrange code ssV
Sreenivasa chary Thatikonda, F. N. De Oliveira-Lopes, A. Mustonen +3
The super simple Vlasov (ssV) code was developed to study instabilities, turbulence, and reconnection in weakly magnetized plasmas, such as the solar wind in the dissipation range…
Simulations of edge and SOL turbulence in diverted negative and positive triangularity plasmas
P. Ulbl, A. Stegmeir, D. Told +3
Optimizing the performance of magnetic confinement fusion devices is critical to achieving an attractive fusion reactor design. Negative triangularity (NT) scenarios have been show…
