Turbulence of second sound waves in superfluid He II
We communicate the results of numerical studies of acoustic turbulence in a system of slightly
 dissipating, nonlinear second sound waves in superfluid He II. It is shown that at sufficiently high
 amplitude of the external driving force the power-like energy distribution over freque...

| description | We communicate the results of numerical studies of acoustic turbulence in a system of slightly
dissipating, nonlinear second sound waves in superfluid He II. It is shown that at sufficiently high
amplitude of the external driving force the power-like energy distribution over frequency is formed
in the system of second sound waves. This distribution is attributed to formation of the acoustic
turbulence regime in the system. The interval of frequencies in which the distribution has a
power-like form is expanded to high frequencies with increasing the amplitude of the driving
force. The distribution of the energy inside this interval is close to Eω~ 2. It is shown that the
distribution of energy Eω depends on the value of the nonlinearity coefficient of the second sound,
but does not depend on the sign of the coefficient, i.e., the coherent structures (shock waves) do
not contribute to the statistical properties of the turbulent state.
