Physics Today article on Supersolid Helium

Publication date: Thu, May 21, 2015 - 11:51am

An article by Professor Robert Hallock in the May issue of Physics Today titled Is Solid Helium a Supersolid? discusses the unusual properties of solid Helium. In experiments done in his group (see image) they find that helium atoms flow through a sample of solid helium, but in a fashion dramatically unlike the behavior previously predicted for supersolids. Theoretical work in the department, led by Boris Svistunov and Nikolay Prokof'ev has been instrumental in the development of new understanding of solid helium.
