Tuesday, June 10, 2008 - 08:21 in Physics & Chemistry

Who would think that the froth on a morning cup of cappuccino has a lot in common with superconductors? Physicists have found that the bubble-like arrangement of magnetic domains in superconducting lead exhibits patterns that are very similar to everyday froths like milk on a fancy coffee. The similarities between "suprafroths" and conventional froths establish suprafroths as a model system for the study of all froths.
