Gerhart Lüders

from Wikipedia, the free encyclopedia

Gerhart Lüders (born February 25, 1920 in Hamburg , † January 31, 1995 in Göttingen ) was a German theoretical physicist who mainly worked on quantum field theory , where he was known for the discovery and general proof of the CPT theorem . This theorem is also called Pauli-Lüders theorem and is one of the most fundamental rules in particle physics .

Lüders received his doctorate in Hamburg in 1950 and completed his habilitation in 1954 at the University of Göttingen . In the same year he proved the CPT theorem in the form that in a relativistic quantum field theory with parity invariance the CT invariance also applies. Wolfgang Pauli , who like John Bell formulated this theorem independently of Lüders, gave one a little later more general proof. With Bruno Zumino in 1958 Lüders rigorously derived the so-called spin statistics theorem and again the CPT theorem, this time from general field theoretical axioms of relativistic quantum field theory (assumptions such as local causality). From 1957 to 1960 he was group leader at the Max Planck Institute for Physics in Munich (of which he remained an external member from 1961) and from 1960 until his retirement in 1982 he was a professor in Göttingen.

Lüders also examined the quantum mechanical measurement process mathematically and dealt with superconductivity .

In 1959 he received the Physics Prize of the Academy of Sciences in Göttingen and in 1966 the Max Planck Medal . Since 1962 he was a member of the Academy of Sciences in Göttingen.
