Le physicien français Claude Cohen-Tannoudji, colauréat du prix Nobel en 1997 pour ses travaux sur le refroidissement des atomes, est décédé jeudi à l'âge de 93 ans, a annoncé sa famille vendredi à l'AFP.

Professeur au Collège de France et membre de l'Académie des sciences, il avait reçu le prix Nobel conjointement avec les Américains Steven Chu et William D. Phillips, pour le développement de méthodes servant à refroidir et à confiner des atomes à l'aide de lasers.

«Des progrès spectaculaires»

Les recherches ont «permis des progrès spectaculaires dans le domaine des atomes froids», notamment dans la précision des horloges atomiques, souligne le Laboratoire Kastler Brossel, unité mixte de recherche de l'École normale supérieure, de Sorbonne Université, du Collège de France et du Centre national de la recherche scientifique (CNRS), où il a longtemps travaillé.

Né le 1er avril 1933 à Constantine (Algérie), le professeur Cohen-Tannoudji a également joué un rôle important pour le rayonnement de la physique atomique et de l'optique quantique, en transmettant son savoir à de nombreux jeunes physiciens, dont les Nobel français Serge Haroche et Alain Aspect. À l'occasion de son prix Nobel, Jacques Chirac, alors président de la République, avait ainsi salué en lui «l'enseignant» dont les cours et les publications ont «enthousiasmé, année après année, étudiants et chercheurs».
