Jean Dalibard

Jean Dalibard ( born December 8, 1958) is a French physicist.


Dalibard worked with Alain Aspect and Gérard Roger at the Laboratoire Charles Fabry in Orsay. In 1982, she reported together in an experimental test of the EPR effect after the first time that Bell 's inequalities are violated.

In 1986 he received his PhD under the guidance of Claude Cohen-Tannoudji about the manipulation of atoms by laser beams. Dalibard works at the CNRS in the study of Bose -Einstein condensates and being a professor at the École Polytechnique ( Laboratoire Kastler - Brossel ).

In addition to the development of methods of laser cooling and atom traps he deals with Bose - Einstein condensates (BEC ), for example, the behavior of vortices in rotating BEC. He also deals with low-dimensional many-body systems such as the Kosterlitz - Thouless - Berezinski transition in atomic gases in two dimensions.

He is a member of the Academy of Sciences in France. In 2012 he was awarded the Davisson -Germer Prize, in 2000 he received the Prix Jean Ricard, 2010 the Prix des trois physiciens and 2009 Blaise Pascal Medal. In 2012 he was awarded the Max Born Award.

In 2010 he was a visiting scientist at Trinity College, Cambridge. In 1991 he was at NIST with William D. Phillips.
