Asim Orhan Barut

from Wikipedia, the free encyclopedia

Asim Orhan Barut , mostly AO Barut cited, (born June 6, 1926 in Malatya , Turkey , † December 5, 1994 in Boulder , Colorado ) was a Turkish-born American theoretical physicist.

Barut studied physics at the ETH Zurich with a diploma in 1949 and a doctorate in 1952 ( electron-optical and statistical behavior of lattice multipliers ). He started out as an experimental physicist, but then turned to theoretical physics. He was a postdoc at the University of Chicago in 1953/54 . In 1954 he became an assistant professor at Reed College and in 1956 at Syracuse University .

From 1959 to 1960 Barut was a research fellow at the European Organization for Nuclear Research (CERN) in Geneva , Switzerland.

From 1962 he was a professor at the University of Colorado in Boulder , where he retired in 1994. 1970 to 1972 he was co-director of the Institute for Theoretical Physics in Boulder and he was Distinguished Research Lecturer at the university. Among other things, he was visiting professor at the University of Munich, at the Max Planck Institute for Physics in Munich, in Ankara, Warsaw, Stockholm, Caracas, Edinburgh. He died of a heart attack.

Barut had a wide range of interests and dealt with classical field theory, quantum optics, S-matrix theory, quantum electrodynamics and quantum mechanics with a special focus on group theoretical methods and fundamental questions. He also went unorthodox ways, for example by pursuing an approach to quantum electrodynamics without a second quantization of the electromagnetic field or a theory of hadrons as bound states of leptons via short-range magnetic resonances.

Barut has authored over 500 scientific articles, wrote six books, and edited 25 others (many of which emerged from the Boulder Summer Schools on Theoretical Physics, which he led, and the NATO Advanced Study Institutes). In 1991 he received the Age of Science Award from the Turkish Minister of Education and in 1982 the TÜBITAK science award . He also had an honorary doctorate in Turkey (1987). In 1966 he became a Fellow of the American Physical Society .

With Abdus Salam he was one of the founders of the International Center for Theoretical Physics in Trieste and was a frequent guest there. He also founded a center for theoretical physics in Edirne , Turkey, which he wanted to expand into a center similar to that in Trieste shortly before his death. He was the co-editor of Foundations of Physics .

He had been married to Pierette Gervaz since 1954 and had two daughters and a son. In 1962 he became a US citizen.

He was editor of the collected works of Alfred Landé and EU Condon .
