Giorgio Parisi
Giorgio Parisi (born August 4, 1948 in Rome ) is an Italian physicist and university professor .
life and work
Parisi graduated from La Sapienza University in Rome in 1970 with a degree in physics . His supervisor was Nicola Cabibbo . He then worked until 1981 as a researcher at the Laboratori Nazionali di Frascati, which he left for research stays at Columbia University (1973-1974), the Institute des Hautes Etudes Scientifiques (1976-1977) and the École normal supérieure (1977-1978). 1981 to 1992 he was professor of theoretical physics at the University of Tor Vergata . Since 1992 he has been Professor of Quantum Physics at La Sapienza .
Parisi works in various branches of physics, such as high energy physics , quantum chromodynamics , the theory of phase transitions , statistical mechanics , mathematical physics , string theory and spin glasses . In studies of the scale of injury (Engl. Scaling violation) in deep inelastic scattering, he presented Guido Altarelli equations for the scale dependence of Parton density functions on ( DGLAP equations ). Later he investigated quantum chromodynamics on the grid with the help of the supercomputer APE 100 (Array Processor Experiment, also Italian bee) . By using the so-called quenched approximation , i.e. neglecting the vacuum polarization , it became possible to calculate the mass spectrum of the hadrons with an accuracy of 10 percent.
In the theory of phase transitions , Parisi developed a new method for calculating critical indices and critical exponents . He investigated spin glasses and found, with the revival of the mathematical concept of the ultrametric structure of complex systems, approaches that can also be used in biology ( neural networks , folding of copolymers , immunity ) and combinatorial optimization . He also set up a stochastic differential equation for growth in random accumulations, the Kardar-Parisi-Zhang equation (KPZ).
He is married and has two children.
