Abstract:

The temperature variations of first-, second- and third-sound velocity and attenuation coefficients in one-dimensional superfluid helium are evaluated explicitly for very low temperatures and frequencies omega s tau 1, where omega s is the sound frequency and tau the characteristic time, by using the collisionless kinetic equation and superfluid hydrodynamic equations with the energy dissipation effect. The leading terms for these sounds vary as T2, and the ratio of second-sound to first-sound becomes unity as the temperature decreases to absolute zero.
