Bernard Julia

Bernard Julia (born 1952 in Paris) is a French theoretical physicist who has made contributions to the theory of supergravity.

[1][2] He graduated from Université Paris-Sud in 1978, and is directeur de recherche with the CNRS working at the École Normale Supérieure.

[3] Shortly afterwards, Cremmer and Julia constructed the classical Lagrangian for four-dimensional N=8 supergravity by dimensional reduction from the 11-dimensional theory.

[4][5] Julia also studied spontaneous symmetry breaking and the Higgs mechanism in supergravity[6][7] Other work includes a study, with Anthony Zee, of particles called dyons that carry both electric and magnetic charges[8] and many papers on string theory, M-theory, and dualities.

In 1986, Julia was awarded the Prix Paul Langevin of the Société Française de Physique.
