Claude Cohen-Tannoudji
Claude Cohen- Tannoudji ( born April 1, 1933, Constantine, Algeria ) is a French physicist. For the cool and trap atoms with laser light, he received together with Steven Chu and William D. Phillips the 1997 Nobel Prize in Physics.
Life
Cohen- Tannoudji comes from a Jewish family who lived in the 16th century in Algeria, since 1970 as a French citizen. 1953 to 1957 he studied at the École normale supérieure first mathematics, turned, however, after the lectures of the Nobel laureate Alfred Kastler of physics. In 1957 he completed his studies with a diploma ( Agrégation ) and produced 28 months military service. Since 1960 he worked as a researcher for the Centre National de la Recherche Scientifique (CNRS ). In 1962 he received his doctorate. Since 1962 he has taught at the University of Paris IV 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 and in 1988 Lorentz professor at the University of Leiden.
Services
The 1977 published two-volume monograph Méchanique Quantique who wrote Claude Cohen-Tannoudji, Bernard Diu and Franck, together with Laloë heard still the standard works in the field of quantum mechanics.
With Steven Chu, William D. Phillips developed Cohen Tannoudji a method atoms can be cooled with by the atom beam propagating along the axis of an alternating magnetic field. With this technique, the atom beam is decelerated and the atoms can be captured in a trap. Applications of this method in the development of precise atomic clocks; they can also be used for precise location measurement, and in space navigation.
