Space Daily (Oct. 27) -- An ultrapure material taken to pressures greater than that in the depths of the ocean and chilled to temperatures colder than outer space has revealed an unexpected phase transition that crosses two different phase categories. The new phases were named topological phases, while the traditional phases described by Landau's theory are called broken symmetry phases, says Eduardo Fradkin, a professor of physics and director of the Institute for Condensed Matter Theory at Illinois. Fradkin participated in the research and is a co-author of the paper. Also: R&D Magazine (Oct. 27), NYC Today (Oct. 27).
