The dramatic effect of quantized vortices in superfluid helium on the rate of coalescence of suspended impurities has been predicted; such catalytic process should result in formation of fiber-like structures having primarily ...

Acoustic radiation pressure is thought to be very useful for solid ⁴He experiment under the microgravity. We observed that solid-liquid interface of ⁴He was manipulated by the acoustic wave. We applied the sound pulse ...
