Research Interests



Driven magnetic field carpet for an isothermal atmosphere.
arxiv:1611.03325 ]

Initial magnetic field for sheared relaxation experiments (Longbottom)
Initial magnetic field for the sheared field configuration with Sb = 1 together with the distorted grid box. [ arXiv:1611.0332 ]

Initial magnetic field for relaxation experiments
GLEMuR (Gpu-based Lagrangian mimEtic Magnetic Relaxation code) is now avialabe at github with a minimal documentation and howto. For details about the methods and results see here.


Ideal relaxation of an initially twisted magnetic field with net twist 0. The initially twisted field undergoes an evolution which reduces the free magnetic energy and the strength of the Lorenz force resulting in a force-free state of minimal energy. The used code is GLEMuR.

Helical small-scale turbulent motions lead to an enhancement of magnetic energy. First the small-scale field grows then the field of the largest scale. Due to the conservation of magnetic helicity the large-scale field grows only on resistive time scales.

2D hydrodynamics simulation of a Kolmogorov flow with high Reynolds number. A small initial disturbance in the velocity field gets increased by the instability. The colors represent vorticity.


Decay of the Borromean rings in resistive MHD. Two helical structures arise in corners of the simulation domain. Their magnetic helicity is of opposite sign, since the total magnetic heilcity is 0.
