2018年12月10日 · The researchers repeated their experiments with solid helium-3 and observed that the rate of flow decreased with decreasing temperature, exactly as expected for a normal solid.

2006年10月24日 · — A deceptively simple experiment, recently published in the journal Science, has moved physics one step closer to explaining the odd behavior of supersolid helium. The unusual state of matter – in which a portion of the atoms are able to flow through a solid crystal with no resistance – was predicted as early as 1969 but not observed ...

Figure 1: Cell used to study the growth of solid helium from superfluid helium. Helium is admitted to the solid chamber S through capillaries 1 and 2 (heat-sunk only at 4 K) which first lead to liquid reservoirs atop thin porous glass (Vycor) rods V1 and V2.

2015年5月1日 · Recent experiments suggest that helium-4 atoms can flow through an experimental cell filled with solid helium. But that incompletely understood flow is quite different from the reported superfluid-like motion that so excited physicists a decade ago.

2012年2月2日 · The ILL experiments by Lauter's team studied a 3 by 5 centimeter sample of solid helium-4 powder condensed in a matrix of highly porous aerogel. Previous experiments have indicated that the supersolid effect would appear only in a crystal that is perturbed (i.e., made to deviate from its ideal structure).

Here we report observation of superflow in bulk solid helium. Our experiment shows that the superfluid-like behavior is a general and intrinsic property of solid helium and not the result of confinement in any particular medium.

2004年9月24日 · Here we report observation of superflow in bulk solid helium. Our experiment shows that the superfluid-like behavior is a general and intrinsic property of solid helium and not the result of confinement in any particular medium.

The initial experiments by Sir Francis Simon at Oxford University and by Keesom and their collaborators focused on the melting curve, the specific heat, and the thermal conductivity of solid helium as a test of our early understanding of solids.

2009年5月1日 · On page 632, Hunt et al. (6) report their observation of the onset of remarkable ultraslow dynamics on cooling samples of solid helium, which constitutes new evidence for glass-like behavior. They reveal a subtle interplay between this glassiness and the observed supersolid-like mechanical responses.

2006年10月1日 · In the experiment by Balibar and co-workers 2, a modern version of the classic barometer was filled with solid helium and immersed in a bath of pressurized liquid helium, so that one could...
