Hans-Jürgen Borchers

Hans -Jürgen Borchers ( born January 24, 1926 in Hamburg, † 10 September 2011 in Göttingen ) was a German theoretical physicist who worked mainly on quantum field theory with the rigorous methods of mathematical physics.

Life

Borchers received his doctorate in 1956 with Wilhelm Lenz at the University of Hamburg with the labor studies on field equations different spins and their energy eigenvalues ​​in the Coulomb field. From 1961 to 1963 he was in Princeton at the Institute for Advanced Study. In 1966 he became professor of theoretical physics at the Georg -August- University Göttingen, succeeding Friedrich Hund. In 1991 he became Professor Emeritus.

From him the Borchers classes originate in quantum field theory. It involves equivalence classes of local fields. Borchers showed that two fields, which are " relatively locally " to a local field, and are relative to one another locally, and thus locally. Such relative to each local fields with the same time -evolution operator U have the same S- matrix.

In 1995 he received the Max Planck Medal. He was a member of the Göttingen Academy of Sciences.

Among his students was one of Jacob Yngvason.
