Bretislav Friedrich

Professor of Physics
PhD in Chemical Physics 1981, Prague
Bretislav Friedrich's research revolves around interactions of molecules with and in electric, magnetic, and optical fields and their combinations. The following specific research topics are currently being pursued: (1) supersymmetry and eigensurface topology of molecules in combined electric, magnetic, and optical fields; (2) Stark spectroscopy of molecular complexes created and probed in He nanodroplets; (3) quantum computing with molecules, (3) manipulation of molecules by means of external fields; (4) molecular collisions in fields; (5) spectroscopy and imaging of molecules in fields; (6) cold/slow molecules. Although chiefly theoretical (with a predilection for an analytic approach), the research is closely linked to ongoing experiments. For more, please see Research.
