André Neveu (French: [nəvø]; born 28 August 1946) is a France physicist working on string theory and quantum field theory who coinvented the Neveu–Schwarz algebra and the Gross–Neveu model.
Biography
Neveu studied in Paris at the École Normale Supérieure (ENS). In 1969 he received his diploma (Thèse de troisième cycle) at University of Paris XI in Orsay with Philippe Meyer and Claude Bouchiat and in 1971 he completed his doctorate (Doctorat d'État) there.
In 1969 he and his classmate from ENS and Orsay, Joël Scherk, together with John H. Schwarz and David Gross at Princeton University, examined divergences in one-loop diagrams of the bosonic string theory (and discovered the cause of tachyon divergences).[1] From 1971 to 1974 Neveu was at the Laboratory for High Energy Physics of the University of Paris XI where he and Scherk showed that spin-1 excitations of strings could describe Yang–Mills theories.[2] In 1971, Neveu with John Schwarz in Princeton developed, at the same time as Pierre Ramond (1971), the first string theory that also described fermions (called RNS formalism after its three originators).[3] This was an early appearance of the ideas of supersymmetry which were being developed independently at that time by several groups. A few years later, Neveu, working in Princeton with David Gross, developed the Gross–Neveu model.[4] With Roger Dashen and Brosl Hasslacher, he examined, among other things, quantum-field-theoretic models of extended hadrons and semiclassical approximations in quantum field theory which are reflected in the DHN method of the quantization of solitons. From 1972 to 1977 Neveu was at the Institute for Advanced Study while spending half of the time in Orsay. From 1974 to 1983 he was at the Laboratory for Theoretical Physics of the ENS and from 1983 to 1989 in the theory department at CERN. From 1975 he was Maitre de recherche in 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 L2C, Laboratory Charles Coulomb). In 1994/5 he was a visiting professor in the University of California, Berkeley.
In 1973, Neveu received the Paul Langevin Prize of the Société Française de Physique.[5] In 1988 he received the Gentner-Kastler Prize awarded jointly by the Société Française de Physique and the Deutsche Physikalische Gesellschaft (DPG).[6]
Neveu is married and has three children.

The version of Neveu and Schwarz differed from that of Ramond in the boundary terms. By the choice of the boundary terms they obtained fermion pairs to produce a model of the pion, a boson. An important advantage of this string theory at that time was also that the unphysical tachyon of the bosonic string theory was eliminated.
