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…
An asymptotic-preserving five-moment two-species plasma model coupled to an external magnetohydrodynamic solver
Magnus Deisenhofer, Aleksandr Mustonen, Simon Lautenbach +1
The paper presents an asymptotic‑preserving method that couples a two‑species five‑moment fluid plasma model to an ideal magnetohydrodynamic solver, enabling efficient global simul…
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…
Investigating the Lower Hybrid Drift Instability in Reconnecting Current Sheets Using a Hybrid Kinetic Model (ssV Code)
S. Thatikonda, F. N. De Oliveira-Lopes, A. Mustonen +3
We investigate the nonlinear evolution of the lower hybrid drift instability (LHDI) in reconnecting current sheets using a hybrid kinetic simulation model implemented in the Super…
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…
