Claude Cohen-Tannoudji
Claude Nessim Cohen-Tannoudji (born April 1, 1933 in Constantine , Algeria ) is a French physicist . For cooling and trapping atoms with laser light, he received the 1997 Nobel Prize in Physics together with Steven Chu and William D. Phillips .
Life
Cohen-Tannoudji comes from a Jewish family who had lived in Algeria since the 16th century , as a French citizen since 1870 ( Décret Crémieux ). 1953-1957 he studied at the Paris Ecole Normale Supérieure first mathematics , but turned at the Nobel laureate to lecture Alfred Kastler of physics to. In 1957 he completed his studies with a diploma (Agrégation) and did 28 months of military service. From 1960 he worked as a scientist for the Center National de la Recherche Scientifique (CNRS). In 1962 he received his doctorate. Since 1962 he has taught at the University of Paris IV . In 1973 he became a professor at the Collège de France , where he holds the chair for atomic and molecular physics.
In 1976 he was Loeb Lecturer at Harvard University and in 1988 Lorentz Professor at Leiden University.
Services
The two-volume monograph Mécanique Quantique , published in 1977 , which Claude Cohen-Tannoudji wrote together with Bernard Diu and Franck Laloë, is still one of the standard works in the field of quantum mechanics .
Together with Steven Chu and William D. Phillips, Cohen-Tannoudji developed a process with which atoms can be cooled by spreading the atomic beam along the axis of an alternating magnetic field. With this technique, the atomic beam is slowed down and the atoms can be trapped in a trap . This method is used in the development of precise atomic clocks ; it can also be used for exact positioning and in space navigation.
