Klaus Fredenhagen (born 1 December 1947) is a German theoretical physicist who works on the mathematical foundations of quantum field theory.[1]
Biography
Klaus Fredenhagen was born on 1 December 1947 in
professor emeritus and has continued to be active in research.[5]
Scientific career
His research interests are algebraic quantum field theory and quantum field theory in curved spacetime. In 1981 he proved the existence of antiparticles in massive quantum field theories without using the CPT-invariance.[6] In 1990 he and Rudolf Haag made important contributions to the understanding of the Hawking radiation of black holes on a rigorous mathematical footing.[7] In 1994, together with Sergio Doplicher and John E. Roberts, he investigated the mathematical foundations of quantum gravity in terms of the quantum structure of spacetime at the
Planck scale.[8] In 1996, together with Romeo Brunetti, he started working on the generalization of the Epstein-Glaser renormalization procedure of interacting quantum field theories in curved spacetime using techniques from the microlocal analysis.[9] He is currently working, together with Detlev Buchholz, on a new C*-algebraic approach to interacting quantum field theories.[10]
Honors and awards
In 1987 Klaus Fredenhagen was awarded the physics prize of the
University of Leipzig.[13] In December 2017 the workshop Quantum Physics meets Mathematics was held in honor of his 70th birthday at the University of Hamburg.[14]
