Jean-Loup Gervais

Jean- Loup Gervais ( born September 10, 1936 in Paris ) is a French theoretical physicist.

Gervais studied physics and mathematics in Paris, where he graduated in 1961 and 1965 his doctorate in Orsay Claude Bouchiat and Philippe Meyer. 1966-1968 he as a post- doc at the University in New York City was. As early as 1960 he was with the CNRS, from 1970 as Maitre de Recherche. 1973 to 1985 he was Maître de conférences the École polytechnique.

From 1979 to 1983 and from 1995 to 1998 he was director of the Laboratory of Theoretical Physics at the École normale supérieure. He had been a guest professor at the City College of New York and also, among others, the University of California, Berkeley, at the Isaac Newton Institute in Cambridge (1997), at the University of California, Los Angeles ( UCLA) and the University of California, Santa Barbara.

Gervais dealt with quantum field theory, supersymmetry and string theory. In 1969 he examined (simultaneously with Benjamin Lee) the Renormalisierbarkeit of theories with spontaneous symmetry breaking. In 1971, he presented with Bunji Sakita a supersymmetric Lagrangian invariant under the precursor of string theory, the dual models on. In 1969, he calculated with Daniele Amati and Bouchiat Einschleifendiagramme in the early string theory. He also looked back in the early 1970s with Sakita string theories as conformal field theories in two dimensions and in the 1970s with Sakita Solitonentheorien as field theories of collective excitations such as within the framework of WKB wave functions. In the 1980s he studied soliton ( Skyrmion ) models of quarks in the limit of many color degrees of freedom (large N limit ). He also studied in the 1980s conformal field theories (such as the Liouville field theory ), string theories and two-dimensional quantum gravity in terms exactly integrable systems. With André Neveu he studied in the 1980s also non-critical string theories.

In 1997 he received a high price (Le Prix Créé par l' État ) of the French Academy of Sciences.

His doctoral include the particle Antal Jevicki ( * 1951, Yugoslavia, professor at Brown University) and Adel Bilal.
