Claude Cohen-Tannoudji (born April 1, 1933) is a French physicist and Nobel Laureate. He shared the 1997 Nobel prize in physics for research in methods of cooling and trapping atoms using laser light. He is still an active researcher, working at the √Čcole Normale Sup√©rieure in Paris.

Early life

Cohen-Tannoudji was born in Constantine to Algerian Jewish parents when Algeria was a French territory. After primary and secondary studies in Algiers, Cohen-Tannoudji left Algeria for Paris to attend the √Čcole normale sup√©rieure. His professors included Henri Cartan, Laurent Schwartz, and Alfred Kastler.

In 1958 he married Jacqueline, a high school teacher, with whom he had three children. 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.

Career

Claude Cohen-Tannoudji in 2010

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.

Awards

1979 - Young Medal and Prize, for distinguished research in the field of optics.

1997 - Nobel Prize, for the development of methods to cool and trap atoms with laser light.
