Bernard L. Julia (* 1952 in Paris ) is a French theoretical and mathematical physicist.

Julia studied from 1970 at the École normal supérieure . He received his doctorate in 1978 at the University of Paris-Süd on gauge theories , but since 1973, among others, he has published with André Neveu on polarization through multiple reflection at the interface between two homogeneous media (with another work on elementary particle physics, the subject of his diploma thesis in 1974) and in 1975 with Anthony Zee on Excitations with electric and magnetic charge ( called Dyon ) in non- Abelian gauge theories . In 1976 he was at the Institute for Advanced Study . He is the research director of the CNRS at the École normal supérieure. In 1978, with Eugène Cremmer and Joël Scherk , he constructed supergravity in 11 dimensions. Shortly afterwards he constructed N = 8 supergravity with Cremmer and investigated the Higgs mechanism in supergravity. He was then active in string theory and its further developments.

In 1994 he was awarded the Gay Lussac Humboldt Prize and in 1986 the Paul Langevin Prize .
