Francesco Calogero

Francesco Calogero ( born February 6, 1935 in Fiesole ) is an Italian physicist.

Calogeros father, Guido Calogero, had been banished by the Italian fascists in the 1940s in a village in Abruzzo ( Scanno ). Calogero studied at the University of Rome (La Sapienza ), where in 1958 he was awarded a degree cum laude ( Laurea ). Calogero stayed at La Sapienza in 1976 and became professor of theoretical physics. He was also a visiting professor and visiting scientists in Princeton, Berkeley, at Queen Mary College in London and at the Institute for Theoretical and Experimental Physics ( ITEP ) in Moscow.

Calogero is concerned with questions of mathematical physics, specifically quantum mechanical scattering problems, Soliton Equations and quantum mechanical many-body theory in particular as regards exactly solvable models. A quantum-mechanical many-body system of one-dimensional interacting with each other via repulsive Coulomb particles, which he examined, is after him and Jürgen Moser named ( Calogero -Moser system or Calogero -Moser - Sutherland system additionally according to Bill Sutherland ). Optionally, nor an external harmonic oscillator can be switched to simulate confined in a volume particles. The model is exactly solvable, as demonstrated in 1971 by Calogero in the quantum mechanical case, and Moser in the classical case, and an important model system of mathematical physics with applications in pure mathematics. Exactly soluble one-dimensional many-body systems with exponential interaction had previously been found by Morikazu Toda.

A special Solitonengleichung is named after him and Athanassios Fokas Degasperis. In 1997, he also presented an interpretation of quantum mechanics, which assumes the cause of the quantization fluctuations of space-time due to the gravitational effect of further masses in the universe ( presumption of Calogero ).

Since 1987 he was a member of the Section of Mathematical Physics IUPAP, its secretary from 1990 to 1993 and from 1993 to 1996 its president.

He is committed to disarmament issues and was from 1989 to 1997 Secretary of the Pugwash Conferences. In this capacity he participated in the Nobel Peace Prize for this organization in 1995. 1997 to 2001 he was Head of the Pugwash Council. 1982 to 1992 he was a member of the SIPRI Leitungsrat.
