Abstract

In these lecture I will present very large scale simulations of the dynamics of spin glasses for large samples, about 10^6 points, for a total time of 10^11 Monte Carlo sweep. These results give us the unprecedented possibility of observing the dynamics of a random system for 11 orders of magnitude in time. Different power law exponents are observed for different quantities (including dynamical heterogeneities). The results are compared with theoretical predictions (when available) and with the results coming from the equilibrium properties (when appropriate) measured on systems of size 32^3.

About the speaker

Prof Giorgio Parisi received his PhD from Rome University in 1970. He worked as a researcher at the Laboratori Nazionali di Frascati from 1971 to 1981, and became full professor at Rome University in 1981. He is now professor of Quantum Theories at the University of Rome I, La Sapienza.

Prof Parisi received the Feltrinelli Prize for Physics in 1986, the Boltzmann medal in 1992, the Dirac medal and prize in 1999, the Italian Prime Minister prize in 2002, and the Galileo prize in 2006. He is a fellow of the Accademia dei Lincei, the French Academy of Sciences, the Accademia dei XL and the US National Academy of Sciences.

Prof Parisi has published 3 books and written about 500 scientific publications on reviews. His main research has been in the field of elementary particles, theory of phase transitions and statistical mechanics, mathematical physics and string theory, disordered systems (spin glasses and complex systems), neural networks, theoretical immunology, computers and very large-scale simulations of QCD (the APE project), and non-equilibrium statistical physics.
