Alain Barrat

from Wikipedia, the free encyclopedia

Alain Barrat (* 1971 ) is a French theoretical physicist who studies statistical mechanics in non-equilibrium, disordered systems and complex networks.

career

Barrat received his doctorate in 1996 from the University of Paris VI (Pierre and Marie Curie) under Marc Mézard on spin glasses ( Quelques aspects de la dynamique hors d'équilibre des verres de spin ). As a post-doctoral student , he spent two years at the International Center for Theoretical Physics (ICTP) in Trieste and then conducted research for the Center national de la recherche scientifique (CNRS); first ten years at the laboratory for theoretical physics at the University of Paris-Süd and then at the Center de physique théorique in Marseille . He also works at the Laboratory for Complex Networks at the Institute for Scientific Interchange in Turin .

He explores complex networks and their dynamics with applications on the Internet (where he examined, among other things, Twitter and Facebook networks), transport networks, the spread of epidemics and social networks. Among other things, he developed a renormalization theory for graphs. He also deals with granular media and spin glasses.

In 2009 he received the Paul Langevin Prize .
