Klaus Hepp (born 11 December 1936) is a German-born Swiss theoretical physicist working mainly in quantum field theory. Hepp studied mathematics and physics at Westfälischen Wilhelms-Universität in Münster and at the Eidgenössischen Technischen Hochschule (ETH) in Zurich, where, in 1962, with Res Jost as thesis first advisor and Markus Fierz as thesis second advisor, he received a doctorate for the thesis ("Kovariante analytische Funktionen“) and at ETH in 1963 attained the rank of Privatdozent. From 1966 until his retirement in 2002 he was professor of theoretical physics there. From 1964 to 1966 he was at the Institute for Advanced Study in Princeton. Hepp was also Loeb Lecturer at Harvard and was at the IHÉS near Paris.

Hepp worked on relativistic quantum field theory, quantum statistical mechanics, and theoretical laser physics.[1] In quantum field theory he gave a complete proof of the Bogoliubov–Parasyuk renormalization theorem (Hepp and Wolfhart Zimmermann, called in their honor the BPHZ theorem).[2] Since a research stay 1975/6 at MIT he also worked in neuroscience (for example, reciprocal effect between movement sensors, visual sense and eye movements with V. Henn in Zurich).

In 2004 he received the Max Planck Medal.

gollark: I have some random calculator app on my phone is fairly good and can do basic symbolic calculus, graphing, complex number operations, and probably other things, but not matrices.

gollark: My current calculator can do matrices and complex numbers, but the complex number support is bad (no complex exponentiation, *really*?) and matrices are not well integrated.

gollark: What if osmarkscalculator™?

gollark: `units` does arbitrary unit conversions and basic arithmetic.

gollark: `units` can do... some of that.
