Detlev Buchholz

Detlev Buchholz (born 31 May 1944) is a theoretical physicist. He investigates quantum field theory, especially algebraic quantum field theory. His contributions include the concept of infraparticles.

Buchholz studied physics in Hannover and Hamburg where he acquired his Diplom. In 1970-1971 he was at the University of Pennsylvania. After receiving his PhD in 1972 under Rudolf Haag he worked at the University of Hamburg and was in 1974-1975 at CERN. From 1975 to 1978 he worked as a research assistant in Hamburg, where he got his habilitation in 1977. In 1978-1979 he had a Max Kade grant at the University of California, Berkeley. In 1979 he was a professor in Hamburg and changed to the University of Göttingen in 1997. He retired in 2010 as professor emeritus.

Using the methods of Tomita–Takesaki theory he obtained the split property, a strong result about the locality of the theory, from nuclearity conditions of the theory. ^{[1] [2]}

In 2008 he won the Max Planck Medal. It is awarded annually by the Deutsche Physikalische Gesellschaft (German: German Physical Society)
