The research interests of the Institute for
Theoretical Physics (ITP) lie in the area of non-linear physics and
hierarchical modelbuilding. We apply the methods and concepts of
non-linear dynamics to semiconductor physics, quantum optics and
quantum electronics, soft condensed matter and biological physics.
Statistical physics forms the link between microscopic and
macroscopic physics. Using its tools, we develop and study a hierarchy
of models bridging wide temporal and spatial scales, from microscopic
many-body theory, to macroscopic self-organisation, and to the control
of complex non-linear systems. This contributes significantly to the
TU Science Faculty's special research efforts in nanomaterials, optics
and photonics, and soft matter, which are also supported by the
disciplines of solid-state physics, optics, theoretical chemistry and
The cooperation with external institutes such as the Fritz-Haber-Institut (FHI), Max-Born-Institut (MBI), Weierstrass-Institut (WIAS), Hahn-Meitner-Institut (HMI) and the Physikalisch-Technische Bundesanstalt (PTB) is a strategic cornerstone of the methodological diversity of the ITP.
