Wolf symanzik (Born November 23, 1923 in Lyck, East Prussia, † October 25, 1983 in Hamburg) was a German physicist who dealt with quantum field theory (QFT).

Symanzik grew in Königsberg i. Pr. On. He was called in 1942 and in 1944 in southern France in French captivity, in which he remained in North Africa for three years. Symanzik began studying physics in 1947 at the Ludwig Maximilians University in Munich, but switched to Werner Heisenberg to the Georg August University Göttingen in 1949. In 1952 he received his diploma. At that time he dealt with cosmic radiation and made contributions to the anthology, which was then created at the Max Planck Institute for Physics (MPI) Cosmic radiation (Springer 1953). With his fellow students Wolfhart Zimmermann and Harry Lehmann, he began cooperation, which in the 1950s led to important formalisms of a mathematically stricter version of the quantum field theory Lehmann-Symanzik-Zimmermann Theory , short Lsz-theory , it expresses streuamplitudes through vacuum maintenance values ​​of the field operators). The three were later apostrophized by Wolfgang Pauli as a “field club”.

In 1954 he received his doctorate at Heisenberg with the influential work The Schwinger functional in quantum field theory , whereby he refers to Julian Seymour Schwinger’s epochal work, which had just been released, but also to work by Richard Feynman (Wegintegral) and Freeman Dyson (S-Matrix). Then he was briefly assistant to Heisenberg.

From 1955/56 he was again at the Institute for Advanced Study in Princeton and 1956/57 at the University of Chicago, then in Hamburg, again at MPI in Göttingen and 1959/60 again in Princeton. In 1960/61 he was at Stanford University, in Princeton and Los Angeles and then on Cern [first] (Although he dealt with dispersion relations) before taking on a professorship at the Courant Institute in New York City in 1962. Here he developed (also following ideas from Schwinger), which Euclidian quantum field theory , that is, a formal transformation from the Minkowskiraum to the Euclidean space, which makes connections between QFT and statistical mechanics clear. Vacuum maintenance values ​​of operators correspond to correlation functions, etc. These ideas of the “constructive QFT” later became standard in the grating theories.

In 1968 he moved to the Desy in Hamburg as a senior scientist and examined the mathematical background for the newly discovered scaling behavior of quantum field theories (Callan-Symanzik equation) and spontaneous symmetry in the QFT. He picked up the renamation group ideas from Kenneth Wilson. In particular, he gave the first models for asymptotic freedom, which were soon proven in quantum chromodynamics by David Gross, Frank Wilczek and David Politzer. From the 1970s, he dealt with grid theories.

In 1981 he received the Max Planck Medal of the DPG.
