Constantin Meis is Professor at the National Institute for Nuclear Science and Technology (Saclay, France) and he is appointed as an international expert for the CEA (French Atomic Energy Commission).
He studied physics at the University Paris 7 where he obtained in 1984 the “Maitrise de Physique”, with specialization in Atomic and Nuclear Physics. Then he got the Master Degree (DEA) in Atomic Physics, Quantum Optics and Lasers at Orsay University (Paris Sud) in 1985. He is holder of PhD in Atomic Physics obtained also at Orsay University in 1988 and of HDR (Habilitation à Diriger des Recherches) obtained at Marseille University in 2003.
After his PhD thesis he started his career in 1988 as physicist at the CEA Saclay where he worked on many theoretical studies related to the computational modelling of the electromagnetic waves propagation and absorption in magnetized low temperature metallic plasmas.
After 1995 he participated in the CEA program of nuclear waste disposal by working using atomic scale simulations (DFT and Molecular Dynamics) for the study of radiation effects in materials.
In 2001 he took the head of the Physics and Materials Unit of the National Institute for Nuclear Science and Technology (INSTN – CEA) where he became Professor.
He has done more than a hundred publications and international communications and he is the author of the book “Light and Vacuum” edited by World Scientific in 2014 and of the augmented 2nd Edition in 2017. A resume of the theory that he has developed for the wave-particle (wave-corpuscle) nature of the photons and the quantum vacuum as the electromagnetic field ground state is given in the downloadable publications.
