Sir Anthony Leggett
Sir Anthony Leggett, a former Professor of Physics at the University of Sussex, was awarded the Nobel Prize for Physics jointly with Russians Alexei Abrikosov and Vitaly Ginzburg in 2003 for his work on the theory of superfluids.
It was during his years at Sussex in the 1970s that Professor Leggett, a theoretical physicist, formulated "a decisive theory" explaining how atoms interact and are ordered in the superfluid state. On the basis of his findings, recent studies show how this order passes into chaos or turbulence.
Although now a US resident and citizen, Professor Leggett was born and educated in the UK. He became a Lecturer in Physics at the University of Sussex in 1967. In 1971 he was promoted to Reader and then in 1978 to Professor of Physics. He left Sussex in 1983 to move to the University of Illinois at Urbana-Champaign.
In 2004 he was knighted (KBE) "for services to physics". He also won the 2002/2003 Wolf Foundation Prize for research on condensed forms of matter (with B. I. Halperin).
