报告摘要: At the cross-over between several domains of science and technology, matter-wave optics is the field dealing with the generation and analysis of coherent matter waves. Owing to the recent development of atom cooling techniques and material nanostructure fabrication, this field, as well as atom interferometry and its applications, has quickly grown. Many of the functions previously operated in light optics have been realised in atom optics: atom diffraction and reflection, beam splitters, atom holography, atom lasers, etc. The physical processes allowing one to implement those functions in matter-wave optics will be reviewed, as well as their peculiar characteristics originating in the specific properties of the associated particle: non-zero mass, vacuum dispersion for the “de Broglie” wave, scalar character of the wave, internal atomic degrees of freedom, intrinsic polarisability, etc. Along this viewpoint, novel concepts in the field of matter-wave optics and interferometry will be described, including atom interferometry at the nano-scale, non-diffracting atom waves and negative-index media (“meta-materials”) for matter-wave optics. Their distinct properties (atom beam profile, group velocity characteristics, wave-packet dynamics, matter-wave’s propagation…) will be analysed, comparatively to the equivalent processes in photon optics.
报告人简介:Martial Ducloy, after graduating from Ecole Normale Supérieure, Paris, got his Dr of Science on Optical Pumping with Lasers in the Kastler Laboratory. After two years at MIT as a visiting scientist he came to Univ Paris Nord, where he has held various positions: Director of the Laser Physics Laboratory, Dean for Research, Dean for International Relations. He has also been head of the Physics Centre of “Ecole des Houches”. He is presently Director of Research at CNRS, “Classe Exceptionnelle”. His main research activities have been in laser physics and spectroscopy, nonlinear and quantum optics, cavity QED, and recently atom optics. He has held several responsibilities at the international level: Chair of the Quantum Electronics and Optics Division of the European Physical Society, President of the EPS (2001-3), Initiator of the “World Year of Physics” 2005, member of various physics evaluation panels (European Union, Portugal, South Africa…). He has over 200 publications in peer-referred journals and over 100 plenary conference or invited talks at international meetings, and organised 15 international conferences and workshops. He is a Member of several academies - Academia Europaea, Russian Academy of Sciences and Bulgarian Academy of Sciences.
