Italian theoretical physicist
Erio Tosatti (born 9 November 1943 in Nonantola ) is an Italian theoretical physicist active at the International School for Advanced Studies (SISSA), and at the Abdus Salam International Centre for Theoretical Physics (ICTP) , both in Trieste , Italy . He is a broad-scope theorist who carried out research on a wide range of condensed matter physics phenomena. His early work dealt with optical properties,[ 1] electron energy loss,[ 2] theory of excitons [ 3] and nonlocal dielectric response [ 4] in solids, including layer crystals such as graphite [ 5] and semiconductors ; charge- and spin-density-waves;[ 6] [ 7] [ 8] surface physics in all its aspects, particularly reconstruction,[ 9] roughening[ 10] and melting,[ 11] also in clusters;[ 12] the prediction the Berry phase in fullerene;[ 13] [ 14] the first calculated STM map of graphite,[ 15] now a standard in the field; matter at extreme pressures: carbon ,[ 16] oxygen ,[ 17] [ 18] hydrogen ,[ 19] CO2 ,[ 20] iron at earth core conditions,[ 21] water and ammonia at deep planetary conditions,[ 22] pressure-induced insulator-metal transitions in layer compounds like MoS2 .[ 23] In nanophysics, he and his group predicted helical structures of metal nanowires ;[ 24] [ 25] the spontaneous magnetism of metal nanocontacts,[ 26] including the electronic circumstances for normal or ferromagnetic Kondo effect therein.[ 27] [ 28] His and his collaborator's theory of strongly correlated superconductivity [ 29] [ 30] was recently confirmed in compounds such as Cs3C60. Pioneering papers on quantum annealing [ 31] [ 32] are now basic to current developments in quantum computing . More recently he moved on to the theory of nanofriction,[ 33] a field where he obtained the ERC Advanced Grant MODPHYSFRICT 2013–2019, and subsequently, as co-PI with an experimental group, another ERC Advanced Grant ULTRADISS 2019-2024 .
