Faraday waves and vortices on the surface of superfluid He II

It has been shown that the interaction between Faraday waves excited on the surface of He II by intense vertical vibrations of the sample cell can lead to the emergence of macroscopic vortices on the surface of the superfluid liquid, as in the case of an ordinary classical liquid. Visualization of p...

Summary:It has been shown that the interaction between Faraday waves excited on the surface of He II by intense vertical vibrations of the sample cell can lead to the emergence of macroscopic vortices on the surface of the superfluid liquid, as in the case of an ordinary classical liquid. Visualization of phenomena on the surface of He II by light glass tracers with a diameter of ~0.2 mm localized beneath the surface of He II has allowed observing the emergence of a vortex lattice on the surface of the vibrating superfluid liquid in square and cylindrical cells and the evolution of the vortex structure after switching off the pumping.
