Gert Emil Friedrich Roepstorff (born March 28, 1937 in Hamburg ) is a German physicist and professor emeritus for theoretical physics at RWTH Aachen University .

Life

Roepstorff studied physics at the University of Hamburg , was accepted as a scholarship holder in the German National Academic Foundation and received his doctorate in 1964 under Gustav Kramer (particles with spin in axiomatic quantum field theory ). From 1964 to 1966 he was at the Massachusetts Institute of Technology in Cambridge (Massachusetts) and at the Argonne National Laboratory . In 1967 he returned to the University of Hamburg, where he completed his habilitation in 1971. In 1972 he became scientific advisor and professor for physics in Hamburg and in 1974 was appointed to RWTH Aachen University. Several research stays took him to the Technion (Israel Institute of Technology) in Haifa, Israel. In 1980/81 and 1986/87 he was a visiting member at the Institute for Advanced Study in Princeton , USA. In 2002 he retired.

Roepstorff's interests were in mathematical physics, quantum field theory, statistical physics, the theory of dynamic systems and elementary particle physics . The main research areas were the infrared problem in QED , inequalities in quantum statistics, KMS theory and the Bose gas, ferromagnetism in spin-glass models, long-term behavior, relaxation times and strange attractors in dynamic systems, Liapunov exponents, special path integrals, spontaneous symmetry breaking , quantum dynamic entropy, local anomalies in the QFT , super-connections (in the sense of D. Quillen ) and the Higgs field in the standard model of particle physics.

Most recently he dealt with GUT theories, which are based on supersymmetric generalizations of fiber bundles (with a unitary gauge group) of differential geometry (where the Higgs field is a consequence of a non-vanishing scalar curvature).
