Evolution of the energy flux in a system of nonlinear surface waves in He-II
Abstract:
Evolution of the energy flux in a system of nonlinear surface waves in He-II

The results of experimental studies of turbulent spectra in a wave system on the surface of superfluid He-II in a rectangular cell are presented. It is observed that with intense monochromatic pumping in the non-decay range of the spectrum, the modulation instability of the wave at the pump frequency develops, which can lead to the formation of a flux of wave action directed to the low-frequency range of the spectrum in a discrete wave system. The work was supported by the Russian Science Foundation, Grant No. 17-12-01525.
