(1997) Claude Cohen-Tannoudji

Claude Cohen-Tannoudji (born April 1, 1933) is a French physicist and Nobel Laureate. He shared the 1997 Nobel Prize in Physics with Steven Chu and William Daniel Phillips for research in methods of laser cooling and trapping atoms. Cohen-Tannoudji was born in Constantine, when Algeria was a French territory. After finishing secondary school in Algiers in 1953, Cohen-Tannoudji left for Paris to attend the École normale supérieure. His studies were interrupted when he was conscripted into the army, in which he served for 28 months (longer than usual because of the Algerian War). In 1960 he resumed working toward his doctorate, which he obtained at the end of 1962. After his dissertation, he started teaching quantum mechanics at the University of Paris. His lecture notes were the basis of the popular textbook, Mécanique quantique, which he wrote with two of his colleagues. He also continued his research work on atom-photon interactions, and his research team developed the model of the dressed atom. In 1973, he became a professor at the Collège de France. In the early 1980s, he started to lecture on radiative forces on atoms in laser light fields. He also formed a laboratory there with Alain Aspect, Christophe Salomon, and Jean Dalibard to study laser cooling and trapping.
His work there eventually led to the Nobel Prize in physics in 1997 for the development of methods to cool and trap atoms with laser light, shared with Steven Chu and William Daniel Phillips. Cohen-Tannoudji was the first physics Nobel prize winner born in an Arab country.
