Pierre Coullet (* 1949 in Nice ) is a French physicist who studies nonlinear dynamics , self-organization , turbulence and chaos theory.

Live and act

Coullet did research for the CNRS from 1975 - from 1984 as research director - and was professor at the University of Nice (Sophia Antipolis) at the INLN (Institut Non-Lineare de Nice) from 1987 , of which he was director from 1995 to 2002. From 1995 to 2005 he was a senior member of the Institut universitaire de France . Since 2005 he has been director of the Robert Hooke de Culture Scientifique Institute at the University of Nice.

Coullet and Charles Tresser discovered, independently of Mitchell Feigenbaum, the constant, later named after Feigenbaum, and its universality in the transition to chaos with bifurcation cascades . He also proposed the experimental measurement of the Feigenbaum constant . Coullet dealt with applications of nonlinear dynamics in hydrodynamics , nonlinear optics , chemical reactions, liquid crystals , biological systems and in Bose-Einstein condensation . He worked with the mathematician Gérard Iooss .
