Department of Theoretical Physics (F-1)

Research activities

• In theoretical physics of nuclei, elementary particles and fields research is done into nuclear three-body problems, into effective mesonic and quark models that should account for static and dynamic properties of hadrons, into the usefulness of physical gauges in quantum chromodynamics, into unified theories of particles and fields that inhabit higher-dimensional spacetimes with both Grassman even and odd coordinates, into relativistic theories of extended objects like membranes, and into the prospect for linear transport equations to shed new light on the essentials of quantum mechanics and quantum field theory.

• Research in the area of theoretical solid state physics during recent years has been devoted to the following subjects: models of strongly correlated electron systems related to high-temperature superconductivity (the t-J and Hubbard model, analysed predominantly by exact diagonalization methods), static and dynamic properties of quantum spin and dipolar glasses as well as orientational glasses, the influence of external fields (electric and magnetic) and of finite geometry on the properties of ferro- and antiferroelectrics, and on phase transitions betwen reconstructed and unreconstructed surfaces of noble metals.

• In theoretical biophysics, membranes, phospholipid vesicles and cells are studied. In particular, forces between charged surfaces and shapes of cells are investigated in order to understand the equilibrium properties of membranes.
