He became a Fellow of the American Physical Society in 1997. Professor Vignale’s main areas of research are many-body theory and density-functional theory. He is the author of two books, Quantum Theory of the Electron Liquid and The Beautiful Invisible and has published almost 200 papers.
Interactions among noncondensed bosonic atoms in a trap can cause one species of atoms accelerated by a magnetic field to drag along another species of atoms that would normally not interact with the field. Read More »
