The research focus of the Institute for Applied Physics is on modern optics. In addition to fundamental research, the IAP pursues research activities in application-related fields such as optical data storage, data processing and quantum encryption as well as laser development and laser-based measurement technology. There is also a close connection between the IAP and GSI (Helmholtzzentrum für Schwerionenforschung ) through joint research activities on laser spectroscopy and laser cooling of highly charged ions in storage rings and ion traps.
The main topics of the experimental and theoretical research groups at the IAP include quantum optics, quantum information, cold quantum gases, manipulation of individual quantum systems, laser spectroscopy and laser cooling of stored atoms and ions, nonlinear optic and laser physics as well as experimental solid-state quantum optics.
The Institute for Applied Physics is embedded in the Department of Physics with the main research focus on Modern Optics, Condensed Matter Physics and Nuclear Physics. The research activities are characterized by collaborative research projects and interdisciplinary networking within and outside the TU Darmstadt.
