- Title
Condensed-matter physics: Supersolid helium.
- Authors
Beamish, John
- Abstract
This article focuses on the claim of supersolid behavior observed in Helium, made by E. Kim and M.H.W. Chan in their article "Probable Observation of a Supersolid Helium Phase," published in the January 15, 2003 issue of the periodical "Nature." A sample of solid helium-4, confined in the nano-scale pores of Vycor glass and rotated in a torsional oscillator, underwent a transition below about 175 mK that indicated the onset of "supersolid" behaviour. If it can be confirmed that superflow is occurring in the solid helium, this is a remarkable result indeed. Their claim is sure to generate interest and some controversy as well. They have checked their measurements carefully to ensure that the decoupling they observe is real. They have also done the critical comparison with solid helium-3, for which they expect and see no decoupling.
