个人简介
born in Taranto on June 4, 1945. resident in Trieste, Via Economo, 8
Stefano Fantoni is an Italian theoretical physicist, now retired from the International School for Advanced Studies in Trieste (SISSA), still working in the fields of nuclear physics and low temperature physics.
He is considered among the top three Italian scientists in the field of theoretical nuclear physics.
The common denominator of his research was to go beyond the mean-field models in solving the many-body problems that occurs in quantum Bose or/and Fermi systems, characterized by the presence of strong correlations among their components. In that he has given significative improvements to the many-body theory and in the numerical simulations for quantum fluids. In the seventies he has been the author, together with Sergio Rosati, of the Power Series cluster theory for strongly interacting fermions, known as FR cluster expansion, and later, of the Fermion Hyper Netted Chain (FHNC) integral equations to compute the FR expansion terms at all orders. Such theories have opened up the modern many-body studies on strongly interacting Fermi systems, such as nuclear matter and Quantum fluids. It is due to him and to V. R. Pandharipande and O. Benhar, the extension at all perturbative orders of the so called Correlated Basis Function (CBF) theory, originally developed by E. Feenberg, and the proof of its renormalizability, as well as the first realistic calculation of the one-body Green's Function and the Response functions of Nuclear matter, largely used to explain the experimental results of electron and neutrino scattering on heavy nuclei. Also of great importance are his studies done together with Kevin Schmidt on Quantum Monte Carlo methods for nuclear systems, and particularly the development of the Auxiliary Field Diffusion Monte Carlo (AFDMC) method, heavily used in nuclear and neutron matter calculations.
He was born in Taranto on 4 June 1945 and attended the high school in Livorno and the university studies in Pisa. He graduated in Physics in 1968 from the Pisa University, and received his PhD degree in 1970 from the Scuola Normale Superiore. He first worked as an assistant lecturer at the University of Pisa from the first of November 1970 and then as Associate Professor since 1972. In 1986 he became full professor and three-month later he was given the chair of Nuclear Physics at the University of Lecce.
From 1991 to 2000 he acted as Director of the Interdisciplinary Laboratory of the International School for Advanced Studies, SISSA in Trieste. In 2004 he was elected and nominated as SISSA Director, duty that he has covered until November 2010. In 2011 He was nominated as President of ANVUR (the Italian Agency for the evaluation of the university and of the research) duty that he has covered until 2016. In 2016 he was nominated as President of the International Foundation for the Development of Freedom of Science (FIT) in Trieste, duty that he is still covering. In 2022 he has been nominated as Secretary General for the Administrative affairs of the International Union of Physics and Applied Physics (IUPAP)
He has published about 400 amongst papers, books and invited talk contributions, with more than ten thousands citations, an index factor of 47 and an i10-factor of 114.
