Klaus Hepp

from Wikipedia, the free encyclopedia

Klaus Hepp (born December 11, 1936 in Kiel ) is a German-born Swiss theoretical physicist who mainly works in the field of quantum field theory .

Hepp studied mathematics and physics at the Westfälische Wilhelms-Universität in Münster and at the Eidgenössische Technische Hochschule (ETH) in Zurich , where he received his doctorate from Res Jost in 1962 ( covariant analytical functions ) and completed his habilitation in 1963. From 1966 until his retirement in 2002 he was Professor of Theoretical Physics there. From 1964 to 1966 he was at Princeton at the Institute for Advanced Study . Hepp was also a Loeb Lecturer at Harvard and at IHES near Paris .

Hepp dealt with relativistic quantum field theory, quantum theoretical statistical mechanics and theoretical laser physics. In quantum field theory, he gave a complete proof of the Bogoljubow-Parasiuk renormalization method (Hepp and Wolfhart Zimmermann also called BPHZ method in honor of him). Since a research stay at MIT in 1975/6 , he has also worked on neurosciences (for example the interaction between movement sensors, visual sense and eye movements with V. Henn in Zurich).

In 2004 he received the Max Planck Medal .
