Variational Formulation of a Hybrid Kinetic and Gyrokinetic Model for Astrophysical and Laboratory Plasmas
F. N. deOliveira-Lopes, S. C. Thatikonda, D. Told +5
We present a Lagrangian model that encapsulates fully kinetic ions and gyrokinetic electrons for solar wind electromagnetic turbulence. Using a consistent method, where both electr…
An asymptotic-preserving five-moment two-species plasma model coupled to an external magnetohydrodynamic solver
Magnus Deisenhofer, Aleksandr Mustonen, Simon Lautenbach +1
Accurately modeling collisionless space plasmas requires capturing small-scale kinetic effects while keeping global-scale simulations computationally tractable. Traditional multisc…
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…
Geometrical Formulation of Hybrid Kinetic and Gyrokinetic Hamiltonian Field Theory for Astrophysical and Laboratory Plasmas
Felipe Nathan deOliveira-Lopes, Daniel Told, Karen Pommois +3
In the present work, a consistent Lagrangian model that encapsulates fully kinetic ions and gyrokinetic electrons for solar wind electromagnetic turbulence is formulated. Using a c…
