Observation of acoustic turbulence in a system of nonlinear second sound waves in superfluid ⁴He
We discuss the results of recent studies of acoustic turbulence in a system of nonlinear second sound
 waves in a high-quality resonator filled with superfluid ⁴He. It was found that, when the driving amplitude
 was sufficiently increased, a steady-state direct wave cascade is formed...

| description | We discuss the results of recent studies of acoustic turbulence in a system of nonlinear second sound
waves in a high-quality resonator filled with superfluid ⁴He. It was found that, when the driving amplitude
was sufficiently increased, a steady-state direct wave cascade is formed involving a flux of energy towards
high frequencies. The wave amplitude distribution follows a power law over a wide range of frequencies.
Development of a decay instability at high driving amplitudes results in the formation of subharmonics of
the driving frequency, and to a backflow of energy towards the low-frequency spectral domain, in addition to
the direct cascade.
