| Research Abstract |
When we apply a large amplitude sound to ultra-pure quantum liquid, the unsteady non-linear response with anomalous absorption are found. We have developed the new technique to evaluate it quantitatively and revealed that this absorption is due to the nucleation of the bubble. In addition, we have observed the prelude of the acoustic turbulence. Further developments are expected from these results.
