Wolf Prize Laureate in Physics 2002/3
The Prize Committee for Physics has unanimously decided that the 2002/3 Wolf Prize be jointly awarded to: Anthony J. Leggett and Bertrand I. Halperin.
Bertrand I. Halperin
Cambridge, Massachusetts, USA
“for key insights into the broad range of condensed matter physics: Leggett on superfluidity of the light helium isotope and macroscopic quantum phenomena; and Halperin on two- dimensional melting, disordered systems and strongly interacting electrons.”
The 2002/3 Wolf Prize for Physics is awarded to Professors Bertrand I. Halperin and Anthony J. Leggett for their seminal contributions to the broad range of structures and processes met in condensed forms of matter, a field of study in which understanding of subtle quantum phenomena paves the way to the solid state devices of tomorrow.
Halperin and Leggett have provided a better understanding of the macroscopic properties of materials which rely on non-intuitive quantum effects and interactions, that determine the properties of different states of matter and transitions between them. The theoretical works of both recipients have always been accompanied by experimentation and have had a significant impact on understanding numerous physical phenomena.
Halperin is distinguished for his analyses of dynamic critical phenomena, liquid crystal phases which appear in two-dimensional melting, electric conduction in disordered systems, and strongly interacting electrons in intense magnetic fields, when electrons are confined to moving in two dimensions, or nanostructures patterned in semiconductors.
