Heinrich Leutwyler
Heinrich Leutwyler (born October 12, 1938 in Bern ) is a Swiss theoretical physicist who mainly deals with elementary particle physics (theory of strong interaction ) and quantum field theory.
Leutwyler attended grammar school in Bern and then studied physics, mathematics and astronomy at the University of Bern . After graduating in 1960 he went to the USA a. a. to Princeton . In 1962 he did his doctorate under John R. Klauder (at that time at Bell Laboratories ) on "Generally covariant Dirac equation and associated Boson Fields". In 1965 he completed his habilitation in Bern, where he was assistant professor from 1965 and full professor for theoretical physics from 1969 until his retirement in 2000. In 1983/4 he was dean of the natural science faculty in Bern. Leutwyler was u. a. 1963, 1965 guest residencies at Bell Labs in Murray Hill, 1973/74 at Caltech in Pasadena and 1969/70, 1983/4 and 1996 at CERN . In 1973 Leutwyler, alongside Murray Gell-Mann and Harald Fritzsch, played a key role in the development of quantum chromodynamics (QCD) as a fundamental theory of strong interaction. Later he dealt among other things with the chiral perturbation theory , an effective theory for approximating the QCD at low energies (Gasser-Leutwyler coefficients of the effective chiral Lagrangian function, determination of current quark masses ).
He received an honorary doctorate from the University of Mainz in 1995 , the Humboldt Award in 2000 and the Pomerantschuk Prize in 2011 . He is married and has two children.
