Research interest
- Modelling of multiscale phenomena in materials science, in particular hysteresis and energy-driven pattern formation
- Asymptotic analysis and numerical simulation of non-linear variational and pde models including rigorous
and formal model-reduction techniques, bifurcation theory and amplitude functionals, numerical exploration
of energy landscapes
-
Analytic preconditioners for boundary-element methods for Maxwell equations
Within my thesis, I investigated a
variational model, namely the micro-magnetic energy, that is
applied to describe and understand the behavior of the so-called
magnetization in a ferromagnetic sample. A main purpose was to
develop an understanding of the switching-behavior of the
magnetization and the related hysteresis. The figure below shows
the formation of the so-called concertina pattern in a switching
experiment (first and third row) compared to numerical simulations
(second and fourth row).
