Peter Ulrich Sauer (born May 22, 1938 in Breslau ) is a German theoretical nuclear physicist .

Live and act

Sauer went to grammar school in Fulda and, with a scholarship from the German National Academic Foundation, studied physics from 1958 at the University of Marburg , at the Albert Ludwigs University of Freiburg and at the University of Wales in Swansea (where he obtained a diploma in 1962). In 1964 he made his German diploma in Freiburg, where he received his doctorate in 1966 under Hans Marschall . He then worked as a post-doc in Freiburg, at the Westphalian Wilhelms University in Münster , Carnegie-Mellon University and at the Massachusetts Institute of Technology. In 1972 he completed his habilitation in Freiburg and in 1974 became professor of theoretical physics at the Leibniz University of Hanover . In 1986/87 he was head of the Institute for Theoretical Physics and from 1991/92 and 1999 to 2001 he was dean of the physics faculty. He retired in 2004, but is still active in research (2009).

Sauer is internationally known for investigations into the many-particle problem of nuclear physics, since the 1970s in particular low- nucleon systems (such as deuterium and helium nuclei and their interaction with photons, pions , nucleons) with elaboration of the contributions of the different mesons of nuclear force and QCD degrees of freedom , for example the role of delta isobar excitations and the resulting three-nucleon interactions, with this delta resonance being briefly excited in an intermediate nucleon, or the interaction with pion exchange currents in nuclei. The aim was to model the most realistic nuclear power models possible on a microscopic basis.

Before that, Sauer worked in the 1960s and 1970s with larger systems, Brueckner - Hartree-Fock calculations in finite kernels, where he also worked with Andrew D. Jackson, RJ McCarthy, John Negele , Michel Baranger , and Amand Fäßler . By 2008 he had published around 130 scientific papers.

In 2004 he received an honorary doctorate from Vilnius University .
