Acoustic turbulence of second sound waves in superfluid helium


Institute of Solid-State Physics, Russian Academy of Sciences, Chernogolovka, Moscow Region, Russian Federation

The anomalously strong amplitude dependence of the second sound wave velocity allows an experimental framework to study the behavior of nonlinear waves in a linearly dispersive medium; to investigate the processes of energy transformation from single frequency harmonic pumping into high frequency dissipation edge of spectrum; and to get insight into the formation and decay dynamics of direct and inverse energy cascades.
