Rolling spinners on the water surface
Jean-Baptiste Gorce, Konstantin Y. Bliokh, Hua Xia +3
Angular momentum of spinning bodies leads to their remarkable interactions with fields, waves, fluids, and solids. Orbiting celestial bodies, balls in sports, liquid droplets above…
Tractor beam on the water surface
Horst Punzmann, Nicolas Francois, Hua Xia +2
Can one send a wave to bring an object from a distance? The general idea is inspired by the recent success in moving micro particles using light and the development of a tractor be…
Three-dimensional fluid motion in Faraday waves: creation of vorticity and generation of two-dimensional turbulence
N. Francois, H. Xia, H. Punzmann +2
We study the generation of 2D turbulence in Faraday waves by investigating the creation of spatially periodic vortices in this system. Measurements which couple a diffusing light i…
Inverse energy cascade and emergence of large coherent vortices in turbulence driven by Faraday waves
N. Francois, H. Xia, H. Punzmann +1
We report the generation of large coherent vortices via inverse energy cascade in Faraday wave driven turbulence. The motion of floaters in the Faraday waves is three dimensional b…
Modulation instability and capillary wave turbulence
H. Xia, M. Shats, H. Punzmann
Formation of turbulence of capillary waves is studied in laboratory experiments. The spectra show multiple exponentially decreasing harmonics of the parametrically excited wave whi…
Capillary rogue waves
M. Shats, H. Punzmann, H. Xia
We report the first observation of extreme wave events (rogue waves) in parametrically driven capillary waves. Rogue waves are observed above a certain threshold in forcing. Above…
Phase randomization of three-wave interactions in capillary waves
H. Punzmann, M. G. Shats, H. Xia
We present new experimental results on the transition from the coherent-phase to the random-phase three-wave interactions in capillary waves under parametric excitation. Above the…
Turbulence-condensate interaction in two dimensions
H. Xia, H. Punzmann, G. Falkovich +1
We present experimental results on turbulence generated in thin fluid layers in the presence of a large-scale coherent flow, or a spectral condensate. It is shown that the condensa…
