Giovanni Jona-Lasinio
Giovanni Jona-Lasinio (born July 20, 1932 in Florence ) is an Italian theoretical physicist.
Life
Jona-Lasinio was Professor of Electrodynamics at the University of Padua from 1970 to 1974 and from 1974 Professor of Mathematical Methods of Physics at the University of Rome La Sapienza.
He is known for the Nambu-Jona-Lasinio model, which he examined with Yoichiro Nambu in 1961. The quantum field theoretical model is based on the theory of superconductivity (formation of Cooper pairs ) and describes interacting Dirac fermions with chiral symmetry of the Lagrangian . It shows dynamic symmetry break (of the chiral symmetry), that means break of a symmetry originally present in the Lagrangian through the interaction. It was thus the model for a whole series of later theories with dynamic symmetry breaking in elementary particle physics (as in Technicolor or models for studying quantum chromodynamics ).
A proposal by Di Castro and Jona-Lasinio in 1969 to apply the theory of the renormalization group to the theory of phase transitions influenced the work of Kenneth Wilson in the early 1970s. In the 1980s he investigated the semiclassical limit value of quantum mechanics. He also examined models of statistical mechanics for non-equilibrium systems.
He was a visiting researcher at the University of Chicago in 1959/60 , at CERN in 1964/65 , at the Massachusetts Institute of Technology in 1965/66 , at IHES in 1980/81 and at the University of Paris VI in 1983/84 (Pierre et Marie Curie).
In 2006 he received the Antonio Feltrinelli Prize . He was awarded the Dannie Heineman Prize for Mathematical Physics for 2012 and the Boltzmann Medal for 2013. In 2016 she was elected a member of the Academia Europaea .
