Herbert Wagner (born 6 April 1935) is a German theoretical physicist, who mainly works in statistical mechanics.
Wagner was one of the last students of German theoretical physicist and Nobel prize winner Werner Heisenberg, with whom he worked on magnetism.
The theorem states that continuous symmetries cannot be spontaneously broken at finite temperature in systems with sufficiently short-range interactions in dimensions
Many of his students and junior collaborators now occupy chairs in German universities, including Hans Werner Diehl (Essen), Siegfried Dietrich (Wuppertal, then Max-Planck-Institut für Metallforschung Stuttgart), Gerhard Gompper (Forschungszentrum Jülich), Reinhard Lipowsky (Max Planck Institute of Colloids and Interfaces, Berlin), Hartmut Löwen (Düsseldorf), Klaus Mecke (Erlangen), and Udo Seifert (Stuttgart).
[3] In 2016 he received the Max Planck Medal for his fundamental works on the statistical physics of low-dimensional systems.
