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…
The muphyII Code: Multiphysics Plasma Simulation on Large HPC Systems
Florian Allmann-Rahn, Simon Lautenbach, Magnus Deisenhofer +1
Collsionless astrophysical and space plasmas cover regions that typically display a separation of scales that exceeds any code's capabilities. To help address this problem, the mup…
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…
Stochastic interpolation of sparsely sampled time series by a superstatistical random process and its synthesis in Fourier and wavelet space
Jeremiah Lübke, Jan Friedrich, Rainer Grauer
We present a novel method for stochastic interpolation of sparsely sampled time signals based on a superstatistical random process generated from a multivariate Gaussian scale mixt…
Symmetries and zero modes in sample path large deviations
Timo Schorlepp, Tobias Grafke, Rainer Grauer
Sharp large deviation estimates for stochastic differential equations with small noise, based on minimizing the Freidlin-Wentzell action functional under appropriate boundary condi…
A Parallel Low-Rank Solver for the Six-Dimensional Vlasov-Maxwell Equations
Florian Allmann-Rahn, Rainer Grauer, Katharina Kormann
Continuum Vlasov simulations can be utilized for highly accurate modelling of fully kinetic plasmas. Great progress has been made recently regarding the applicability of the method…
