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 1966 received his degree ( Laurea ) from the University of Rome with Bruno Touschek. As a post - graduate student, he was at the Nuclear Research Centre in Frascati (where you offered him a permanent spot ) and two years at the Massachusetts Institute of Technology and at CERN. In 1974 he became Assistant Professor at the NORDITA in Copenhagen. In 1978 he was again a year at CERN, was from 1979 professor and he FU Berlin and from 1980 to 1986 professor at the University of Wuppertal. From 1986 he was at the NORDITA, where he was a professor and now is Professor Emeritus. Since the NORDITA moved to Stockholm in Stockholm he was half and half at the Niels Bohr Institute in Copenhagen.

He was in the 1970s one of the pioneers of string theory. Among other things, he formulated with Lars Brink and other locally supersymmetric Lagrangian for fermionic strings ( ie those with fermionic excitations, mi half-integer spin ). Previously, the Nambu - Goto action ( according to Yoichiro Nambu, Tetsuo Goto ) had been known for the bosonic string and different groups tried a fermionic action to construct. Regardless formulated and Stanley Deser and Bruno Zumino string theory as a two-dimensional analogue of the general theory of relativity ( with Reparametrisierungsinvarianz the effect on the two-dimensional world sheet (World Sheet) ).

He reported that he then turned away from the string theory, which was considered not promising ( he turned instead instantons in quantum field theory and other things ) and only in 1981 with the publication of works by Alexander Polyakov ( of the effect of Di Vecchia Del Giudice and Fubini for the quantization of strings used, which is why it was known as the Polyakov action) returned there.

In the 2000s he focused on supply models (which are also chiral representations with extension of the AdS / CFT correspondence to low- supersymmetric and non-conformal gauge theories, the construction of four-dimensional effective Lagrangians for low energies from the compactification of magnetized D- brane as in Fermionenspektrum observed the standard model ) and high-energy scattering of closed strings in the framework of the theory of D- branes.

Since 1994, he organized Scandinavian conferences for string theory in the NORDITA.

In 2003 he became a member of the Royal Danish Academy of Sciences.
