We present experiments showing the Rayleigh-Taylor instability at the interface between a
dense magnetic liquid and an immiscible less dense liquid. The liquids are confined in a …

We have calculated the general dispersion relationship for surface waves on a ferrofluid
layer of any thickness and viscosity, under the influence of a uniform vertical magnetic field …

Standing wave patterns that arise on the surface of ferrofluids by (single frequency)
parametric forcing with an ac magnetic field are investigated experimentally. Depending on …

We report on recent progress in understanding the formation of surface protuberances on a
planar layer of ferrofluid in a magnetic field oriented normally to the surface. This normal …

Experimental observation of parametric resonance of a vortex in an active medium is
reported. Unlike the parametric resonance in conservative systems, no parametric pumping …

An interface between two immiscible, nonionic fluids becomes unstable if an electric field is
applied and if the angle between the field and the interface normal is smaller than a critical …

The short-time Fourier transform (STFT) and the continuous wavelet transform (CWT) are
used to analyze the time course of cellular motion in the inner ear. The velocity responses of …

To describe the dynamics of a single peak of the Rosensweig instability a model is proposed
which approximates the peak by a half-ellipsoid atop a layer of magnetic fluid. The resulting …

If a magnetic field normal to the surface of a magnetic fluid is increased beyond a critical
value a spontaneous deformation of the surface arises (normal field instability). The …
