“…Typically, such a description has been very successful in explaining experimental results, e.g., crystallization waves in 4 He [5]. First indications of subtle deficiencies in the standard theoretical treatment were obtained recently in high-resolution interferometric experiments performed on static properties of crystal facets [6]. In this Letter we present data which show that striking shortcomings in the theoretical understanding appear also when dynamic properties of facets are investigated.…”

“…As in our previous optical experiments [10], the lower and upper ends of the cell were sealed with antireflection coated fused silica windows. The cell was connected to a copper nuclear demagnetization stage via a sintered silver heat exchanger with 100 m 2 surface area; the total liquid volume of the setup was 20 cm 3 .…”

We have investigated creation of 4 He crystals from the superfluid phase at the temperature range 2 mK -1.0 K. Statistical nucleation-event distributions in overpressure were found to be broad, asymmetric, and temperature independent below 100 mK. Our statistical analysis agrees with a theoretical model suggesting that solid formation is driven by macroscopical quantum-mechanical fluctuations from a seed preexisting in a cavity on the wall.

“…Recently discovered new growth modes of the facets of 4 He single crystals of nearly equilibrium shape (ECS) make the magnitude of the volume growth rate or its average 1D equivalent exceptionally important [1]. We searched for these growth modes at silver and copper chalcogenides belonging to a group of superionic conductors having high metal atoms diffusivity.…”
