Paolo Di Vecchia
Paolo Di Vecchia (born October 29, 1942 in Terracina ) is an Italian theoretical physicist who deals with elementary particle physics, quantum field theory and string theory.
Di Vecchia received his diploma (laureate) at the University of Rome in 1966 with Bruno Touschek . As a post-doctoral student , he was at the Nuclear Research Center in Frascati (where he was offered a permanent position) and two years each at the Massachusetts Institute of Technology and CERN . In 1974 he became an assistant professor at Nordita in Copenhagen. In 1978 he spent another year at CERN, from 1979 he was professor at the Free University of Berlin and from 1980 to 1986 professor at the Bergische Universität Wuppertal. From 1986 he was at Nordita, where he was a professor and is now professor emeritus. Since Nordita moved to Stockholm, he was half in Stockholm and half at the Niels Bohr Institute in Copenhagen.
He was one of the pioneers of string theory in the 1970s. Among other things, he formulated a locally supersymmetric Lagrangian with Lars Brink and others for fermionic strings (i.e. those with fermionic excitations, with half-integer spin). Previously, the Nambu-Goto effect (after Yōichirō Nambu and Tetsuo Gotō ) was known for the bosonic string and various groups tried to construct a fermionic effect. Stanley Deser and Bruno Zumino also independently formulated string theory as a two-dimensional analogue to general relativity (with reparametrization invariance of the effect on the two-dimensional world sheet).
He reports that he then turned away from string theory, which at the time was not considered to be very promising (instead he turned to instantons in quantum field theory and other things) and only in 1981 with the appearance of the work of Alexander Polyakov (who explained the effect of Di Vecchia, Emilio Del Giudice and Fubini used to quantize strings, which is why it was also known as the Polyakov effect) returned there.
In the 2000s he dealt with the extension of the AdS / CFT correspondence to slightly supersymmetrical and non-conforming gauge theories, the construction of four-dimensional effective Lagrangian densities for low energies from the compactification of magnetized D-brane models (which also provide chiral representations, as they are in the fermion spectrum of the Standard Model) and high-energy scattering of closed strings within the framework of the theory of D-branes.
Since 1994 he has been organizing Scandinavian string theory conferences at Nordita.
In 2003 he became a member of the Royal Danish Academy of Sciences.
