Erio Tosatti

from Wikipedia, the free encyclopedia

Erio Tosatti (born November 9, 1943 in Nonantola ) is an Italian theoretical solid-state physicist.

Tosatti came from a farming family and first attended a technical school in Modena and then studied physics at the University of Modena with a degree in 1967. He then continued his studies at the Scuola Normale Superiore in Pisa, where he studied magna cum laude in 1970 with Franco Bassani received his doctorate. His dissertation dealt with the optical properties of semiconductors, using dispersion relations as in high-energy physics, which was the subject of his thesis in Modena. As a post-doctoral student he was at the University of Rome La Sapienza and at the University of Cambridge , where he met Philip Warren Anderson in 1972/73 , at the University of Stuttgart with Hermann Haken and in 1977 at Stanford University with Sebastian Doniach . In 1977 he was invited by Abdus Salam to set up the group for solid state theory at the ICTP in Trieste. In 1980 he also became a professor at the newly founded International School for Advanced Studies (SISSA) in Trieste. From 2002 to 2003 he was director of the ICTP. In 2014 he retired.

In 1984/85 he spent a sabbatical year at the IBM laboratory in Rüschlikon, where he worked with Karl Alexander Müller and Heinrich Rohrer .

He dealt with a very wide range of topics in theoretical solid state physics. Most recently, he has dealt with friction at the nano-level, metallic and magnetic nanocontacts (including Kondo transport anomalies), Mott insulators and unconventional superconductivity in fullerenes and molecular conductors, electronic correlations on semiconductor surfaces (similar to two-dimensional metals), physics at very high levels Pressure. He predicted the berry phase in fullerenes.

In 2001 he became a Fellow of the American Physical Society , in 2006 a corresponding member of the Accademia dei Lincei , in 2012 a member of the Istituto Lombardo and in 2011 an external member of the National Academy of Sciences . In 2018 he received the Premio Enrico Fermi and in 2005 the Tate Medal for International Leadership in Physics from the American Institute of Physics and in 1997 in Como the The Francesco Somaini Triennial Physics Prize . In 2012 he received an ERC Advanced Grant.
