Biography
E. M. studied Physics at the University of Pisa. On 1989 he won a PhD position in Elementary Particle Physics and Structure of Matter School of Doctorate at the University of Pisa. During the PhD period he collaborated at researches in the Institute of Atomic and Molecular Physics of C.N.R. about "Kinetic Effects of Radiation on Atoms and Gases". The thesis contains the discussion of Light – Induced Drift experiments and of experiments of Resonance Radiation Pressure on a sodium atomic beam and on a sodium vapor in a cell. On October, 1992, he received in Rome the PhD degree. During 1991 he got a permanent position as a Researcher in the University of Siena, in the group of Luigi Moi. On March 2001 he got a position as an Associated Professor in the Faculty of Sciences of the University of Siena, where he was confirmed 3 years later. He is co – author of about 70 papers on refereed reviews and of about 25 refereed proceedings. After the degree and PhD period, in Siena he substantially contributed to the development of a new Laser Spectroscopy laboratory where he started a research activity on Rubidium isotope separation by LID and on LID on lithium vapors, developing a new diode laser source. He also was a little bit involved in the laboratory of Laser assisted collisions among III group atoms. He personally found and studied in detail the Light-Induced Atom Desorption, LIAD, on rubidium and cesium. More recently, LIAD was studied on different organic coatings and on porous glasses. He contributed to the development of a second laboratory devoted to the studies of Laser cooling and trapping and of new spectral sources, in collaboration with INFN groups of Ferrara, Lecce e Bari. He built a Francium Magneto – Optical Trap at the National Laboratories of INFN in Legnaro (Padua). Francium is the best candidate for measurements of Parity non conservation in atoms, as a possible standard model low energy test. Moreover, this short lifetime radioactive atom is still poorly known in his energy level structure. He finally started experiments of Coherence Population Trapping (CPT) on sodium, cesium and rubidium. CPT is a purely quantum effect induced by bichromatic laser radiation on three level systems (lambda- or V- type). He also studied (for the first time in Italy) CPT in nanocells (cells whose thickness is comparable with the laser wavelength).
