André Neveu

from Wikipedia, the free encyclopedia

André Neveu (born August 28, 1946 in Paris ) is a French theoretical physicist who mainly works on string theory and quantum field theory .

Neveu studied in Paris at the École normal supérieure (ENS). In 1969 he made his diploma (Thèse de Troisieme Cycle) at the University of Paris-Süd (Univ. Paris XI) in Orsay with Philippe Meyer and Claude Bouchiat and in 1971 he received his doctorate (Thèse d'Etat) there. In 1969 he was (as a member of the CNRS ) with John Schwarz and David Gross at Princeton University , where he and his French fellow student Joel Scherk examined divergences in single-loop diagrams of boson string theory (they discovered the cause of tachyon divergences). From 1971 to 1974 he was at the Laboratory for High Energy Physics at the University of Paris XI, where he and Scherk showed that the spin-1 excitations of strings could describe Yang Mills theories . Around 1971 Neveu and John Schwarz in Princeton developed the first string theory at the same time as Pierre Ramond (1971), which also described fermions (called NSR string theory after the three authors). At the same time, this was an early work on supersymmetry , introduced around the same time by Russian physicists such as Yuri Golfand . In Princeton he developed the Gross-Neveu model with David Gross and examined a. a. with Roger Dashen and Brosl Hasslacher quantum field theoretical models of extended hadrons and semiclassical approximations in quantum field theory, which is reflected in the DHN method for the quantization of solitons . From 1972 to 1977 he was at the Institute for Advanced Study , spending half of the time in Orsay. From 1974 to 1983 he was at the Laboratory for Theoretical Physics at ENS and from 1983 to 1989 in the theory department of CERN . From 1975 he was Maitre de Recherche at the CNRS and from 1985 Directeur de Recherche. From 1989 he was at the Institute (Laboratory) for Theoretical Physics of the University of Montpellier II (now LPTA, Laboratory for Theoretical and Astroparticle Physics). In 1994/5 he was visiting professor at the University of California, Berkeley .

In 1973 he received the Prix ​​Paul Langevin of the French Physical Society. In 1988 he received the Gentner-Kastler Prize , awarded together with the German Physical Society (DPG), and in 2020 the Dirac Medal of the International Center for Theoretical Physics (ICTP).

Neveu is married and has three children.

By choosing the boundary conditions, they obtained fermion pairs in order to obtain a model of the pion, a boson. An important advantage of this string theory at the time was that the unphysical tachyon of the boson string theory was eliminated.
