Anthony James Leggett (born March 26, 1938), is Professor of Physics at the University of Illinois in Urbana-Champaign. He is widely recognized as a world leader in the theory of low-temperature physics, and his pioneering work on superfluidity was recognized by the 2003Nobel Prize in Physics. He has shaped the theoretical understanding of normal and superfluid helium liquids and other strongly coupled superfluids. He set directions for research in the quantum physics of macroscopic dissipative systems and use of condensed systems to test the foundations of quantum mechanics.
Leggett, 60, who holds the John D. and Catherine T. MacArthur Chair of Physics and is a professor in the U. of I.'s Center for Advanced Study, was named a Fellow along with Stephen Hawking, Sir Roger Penrose, Peter Higgs and Sir Michael Berry.
Leggett's "particularly important contribution" was prominently mentioned in the citation for the 1996 Nobel Prize in physics, which was awarded to two professors at Cornell University and one at Stanford University.
Leggett was honored by the IOP for having made "fundamental contributions to theory of superfluidity in helium-3" and for "contributions to the quantum mechanics of macroscopic systems," according to the institute.
AnthonyJ. Leggett, who was awarded the 2003 Nobel Prize in Physics for his “decisive theory explaining how the atoms (of helium 3) interact and are ordered in the superfluid state,” will give a personal account of his discovery on 17 March 2004 at 11:00 a.m.
Leggett is the John D. and Catherine T. MacArthur Professor and a Center for Advanced Study Professor of Physics at the University of Illinois at Urbana.
Leggett is a pioneer in the theoretical understanding of superfluid helium, high-temperature superconductivity and atomic gases undergoing Bose-Einstein condensation.
