Matter wave interferometry: from concepts to applications (Orale)

Philippe Bouyer (1)

1 Laboratoire Charles Fabry / Optique atomique

Cooled close to absolute zero, atoms move at velocities of or below a few centimetres per second and no longer behave as particles, but as de Broglie waves whose propagation can lead to interference phenomena. This presentation will describe how to observe matter-wave interferences, to reproduce, for example, phenomena found in the propagation of electrons in semiconductors. It will also introduce how to use the interferences to build highly accurate measuring devices and use them for guidance and navigation, or perform accurate test of fundamental physics.
