The Amplitude Equation for the Rosensweig Instability in Magnetic Fluids and Gels
Stefan Bohlius, Harald Pleiner, Helmut R. Brand
The Rosensweig instability has a special character among the frequently discussed instabilities. One distinct property is the necessary presence of a deformable surface, and anothe…
Traveling spatially periodic forcing of phase separation
V. Weith, A. Krekhov, W. Zimmermann
We present a theoretical analysis of phase separation in the presence of a spatially periodic forcing of wavenumber q traveling with a velocity v. By an analytical and numerical st…
Formation of regular structures in the process of phase separation
Alexei Krekhov
Phase separation under directional quenching has been studied in a Cahn-Hilliard model. In distinct contrast to the disordered patterns which develop under a homogeneous quench per…
Growth of surface undulations at the Rosensweig instability
Holger Knieling, Reinhard Richter, Ingo Rehberg +2
We investigate the growth of a pattern of liquid crests emerging in a layer of magnetic liquid when subjected to a magnetic field oriented normally to the fluid surface. After a st…
Long-range effects on superdiffusive solitons in anharmonic chains
C. Brunhuber, F. G. Mertens, Y. Gaididei
Studies on thermal diffusion of lattice solitons in Fermi-Pasta-Ulam (FPU)-like lattices were recently generalized to the case of dispersive long-range interactions (LRI) of the Ka…
Via Hexagons to Squares in Ferrofluids: Experiments on Hysteretic Surface Transformations under Variation of the Normal Magnetic Field
Christian Gollwitzer, Ingo Rehberg, Reinhard Richter
We report on different surface patterns on magnetic liquids following the Rosensweig instability. We compare the bifurcation from the flat surface to a hexagonal array of spikes wi…
