Franz Wegner

Life and work

Franz Wegner received his doctorate in 1968 with Wilhelm Brenig at the Technical University of Munich on the topic " For Heisenberg model in the paramagnetic region and at the critical point ." Subsequently, he was a postdoctoral fellow, inter alia, at the Forschungszentrum Jülich in the group of Herbert Wagner and at Brown University with Leo Kadanoff. Since 1974 he is professor at Heidelberg.

The focus of his scientific work is the statistical physics, in particular the theory of phase transitions and the renormalization group theory. Named after him, " Wegner exponent " is of fundamental importance when it comes to describe corrections to the asymptotic scaling behavior in the vicinity of phase transitions. Wegner "invented" in 1971 also basic gitte rich theoretical models (which any resulting method is nowadays intensively used especially in the simulation of quantum chromodynamics ). In mathematics, the " Wegnersche inequality " for the spectral theory of disturbed systems is known.


Wegner's excellent research is inter alia been honored with the Walter Schottky Prize, the membership of the Heidelberg Academy of Sciences and the Max Planck Medal.
