Alain Aspect, Nobel Prize in Physics 2022

The physicist Alain Aspect, a director at the Laboratory Charles Fabry, within the Institute of Optics located in Orsay, has received the CNRS Gold medal in 2005 for his works on quantum optics and atomic physics. In this film, he recounts his career and describes his researches. He proved the non-validity of the Bell ' s theorem.

In this report, scientists introduce 2019 CNRS Gold Medalist, Thomas Ebbesen and his research. This prestigious French scientific award is awarded to the Franco-Norwegian physical chemist for his highly interdisciplinary work in nanoscience, which covers fields as diverse as carbon materials science, optics, nanophotonics and molecular chemistry. His discoveries have led to technological breakthroughs in optoelectronics, optical communications and biosensors.

The IFRAF gathers six laboratories specialized in the cold atoms manipulation. Since 1984, this physics domain has considerably developed and its applications have increased. This DVD contains two films which explain, in an entertaining way, what are the cold atoms and present one application: the atomic clock.

As a passionate researcher and teacher, Jean Dalibard has never stopped playing with light and matter, which for him, are "the fundamentals of the physical world". He contributed to the emergence and influence of a new discipline, cold atoms. Throughout his career, including thirty years at the CNRS, this eminent researcher has distinguished himself by the originality of his approach. His theory and experiments are at the heart of atomic physics and radiation research. …

This film derives from the Nanosciences and Nanotechnologies DVD. Physicist Etienne Klein traces the history of quantum physics and shows how it gradually forced scientists to question seemingly established notions in classical physics. In particular, classical physics distinguishes two clearly separated categories of objects: particles and waves, whereas a quantum object may behave alternatively as a wave or as a particle. One of the controversial theoretical consequences of quantum…
