Thomas Hoffmann-Ostenhof

Thomas Hoffmann-Ostenhof (born April 4, 1945 in Vienna ) is an Austrian theoretical chemist and mathematician and professor at the Institute for Theoretical Chemistry at the University of Vienna .

After studying chemistry at the ETH Zurich , he did his doctorate in 1974 under Oskar Polansky at the University of Vienna on the subject of the perturbative treatment of the eigenvalue problem , where he has been active ever since. In 1980 he completed his habilitation on the subject of properties of atomic and molecular wave functions . He is on the board of the Erwin Schrödinger Institute for Mathematical Physics .

Among other things, he deals with the quantum mechanical theory of atoms and molecules , in particular the Schrödinger equation . Together with his wife Maria Hoffmann-Ostenhof , he has proven important results on the behavior of the wave function of atoms.

His brother is the Austrian journalist Georg Hoffmann-Ostenhof , his father the biochemist Otto Hoffmann-Ostenhof .
