Siegfried Großmann (born February 28, 1930 in Quednau near Königsberg (Prussia) ) is a German theoretical physicist .

Career

After graduating from high school in Berlin in 1948, Siegfried Großmann studied at the Berlin University of Education in 1951, which he left with a degree as a teacher. He then studied physics, mathematics and chemistry at the Free University of Berlin from 1952 , while at the same time working as a school trainee for elementary, secondary and secondary schools and, after the state examination in 1956, as a trainee lawyer and assessor at a grammar school.

In 1959 he became a research assistant at the University of Berlin with Günther Ludwig , in which he in 1960 with a thesis on the inelastic scattering of hydrogen molecules doctorate was. Just two years later he completed his habilitation at the Free University of Berlin with the thesis Quantum Mechanical Transport Equations : Master's Equation and Boltzmann-Landau Equation . From 1963 Großmann worked as a conservator at the Technical University of Munich . In 1964 he received an extraordinary professorship at the Philipps University of Marburg , where Ludwig had previously moved from the Free University of Berlin. In 1968 Großmann took up a full professorship for theoretical physics here. Among other things, he was the doctoral supervisor of Peter Richter and Detlef Lohse .

He had various professional stays abroad. He also worked in Stuttgart, Ulm, Heidelberg, Göttingen, Erlangen and Dresden, among others. Großmann retired in 1998 . From 1999 to 2005 he was a member of the three-party Ombudsman for Science of the German Research Foundation .

Großmann is married and has three children.

Research areas and interests

Großmann is considered a co-founder of the chaos theory . He made contributions to the description of a laser with the help of nonlinear dynamics. He also published a numerical value for the Feigenbaum constant in 1977 with Stefan Thomae . His work on turbulence contributes to the understanding of the transition from laminar to turbulent flow.

Furthermore, he delivered work in the field of statistical physics , in particular real gases and fluids, non-equilibrium statistics, structure formation processes far from equilibrium, transport processes , stochastic processes and mathematical physics , especially in connection with functional analysis .

Memberships

Großmann was and is a member of numerous commissions and advisory boards:

Awards

In 1995, Großmann was awarded the Max Planck Medal for outstanding achievements in the field of theoretical physics .

For his contributions to chaos theory and for his great scientific reputation, Großmann received the Great Cross of Merit of the Order of Merit of the Federal Republic of Germany from the then Hessian Prime Minister Hans Eichel in 1996 .

In June 2006 Großmann received an honorary doctorate from the University of Duisburg-Essen for his achievements in particular in the theory of turbulence and in non-linear dynamics (chaos research). In December 2011 he received an honorary doctorate from the University of Maribor . He has been the holder of the DPG badge of honor since 2010 and an honorary member of the German Physical Society since 2017 .

He is the bearer of the Karl-Küpfmüller-Ring (1997).

Großmann has been a full member of the European Academy of Sciences and Arts since 1991 . He has been an elected member of the German Academy of Sciences Leopoldina since 1994 . Also in 1994 he became a full member of the Berlin-Brandenburg Academy of Sciences .

Publications

Großmann wrote over 200 publications in various areas of physics.

He is also the author of two textbooks on the mathematical foundations of classical theoretical physics and quantum mechanics :

  • Mathematical introductory course for physics. Teubner, Stuttgart. ISBN 3-519-13074-2 .
