Anthony James Leggett

Sir Anthony James Leggett ( born March 26, 1938 in Camberwell, South London ) is a professor of physics at the University of Illinois in Urbana. He is an acknowledged authority in the theory of low-temperature physics and was honored for his pioneering work in the field of superfluidity with the Nobel Prize for Physics in 2003, which laid the foundations for a theoretical understanding of liquid and superfluid helium and other strongly coupled super fluids.

He thus set the tone for the study of quantum physics of macroscopic dissipative systems and the use of condensed systems to test the foundations of quantum mechanics.

Leggett studied at Oxford University, where he in 1961 took his bachelor's degree in 1964 and his doctorate. After that, he was a postdoctoral fellow at the University of Illinois at Urbana- Champaign, the University of Kyoto, at Oxford and Harvard. In 1967 he was Lecturer and Professor in 1978 at the University of Sussex. Since 1983 he is professor at the University of Illinois at Urbana- Champaign. 1972 to 1974 he was a visiting professor at the University of Tokyo, 1976/77 in Ghana and 1983 at Cornell University.

He is a member of the National Academy of Sciences (since 1997), the American Philosophical Society, the American Academy of Arts and Sciences and the Russian Academy of Sciences, further, he is a Fellow of the Royal Society (Great Britain ), American Physical Society and the American Institute of Physics, as well as an Honorary Fellow of the Institute of Physics ( Great Britain).

In 2002 he received the Wolf Prize in Physics and the 1981 Fritz London Memorial Prize.
