Peter Kramer (physicist)

Peter Kramer ( born March 16, 1933, Quedlinburg ) is a German physicist.

Life

After graduation in 1951 Kramer studied physics in Münster, Tübingen, Bristol and Marburg, where he received his diploma in 1964 and his doctorate. After that, he was a postdoctoral fellow, among others at UNAM in Mexico City, where he worked with Marcos Moshinsky. In Tübingen, he habilitated in 1968. According to another stay at UNAM since 1970 he was a professor at the Institute for Theoretical Physics, University of Tübingen. At the University of Tübingen, he served as Dean and Vice President. Since 1998 he has retired. Kramer is married since 1962 and has two sons.

Work

The research focus of Peter Kramer is in applications of group and representation theory in mathematical physics. He dealt first with issues of nuclear physics. Beginning of the eighties he discovered with his students Roberto Neri, the mathematical model of quasiperiodic tilings of three-dimensional space. The work appeared in 1984 shortly before the work of Dan Shechtman in which for the first time quasicrystals have been reported experimentally. Shechtman was awarded in 2011 for this discovery the Nobel Prize for Chemistry. In recent years, Kramer focuses on cosmological models and three-dimensional space forms. His scientific work includes more than 200 publications.
