Institute for Applied Physics
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.
Our research activities concentrate on quantum optics and quantum information theory. Quantum optical systems allow to realize basic protocols of quantum information processing, such as quantum communication or quantum simulation. Quantum information theory sheds new light on fundamental questions of quantum theory, such as the relation between genuine quantum correlations and classical local realism or decoherence and quantum measurement.

Experimental and theoretical research in the fields of Quantum Optics, Quantum Information, Quantum Technology, and Atomic Physics.
Quantum optical methods are suitable for testing fundamental physics and are building blocks for the application of quantum technologies in sensor technology and metrology. The research topics range from quantum gases to atomic optics, from non-linear quantum optical effects to atomic interferometry and from quantum metrology to inertial sensors.
Our research focuses on the exploitation of nonclassical states of light for both fundamental phenomena in quantum physics and application orientated quantum technologies. This ranges from generation of entangled photon pairs or other genuine quantum states of light towards their application in terms of quantum imaging and sensing. Moreover, laser-written waveguide lattices will serve as testbed for fundamental physics as well for photonic quantum walks.
The research projects on Nonlinear Optics & Quantum Optics deal with coherent light-matter interactions to control optical properties and processes in quantum systems. In particular we aim at novel protocols to implement optical memories as an important prerequisite for optical quantum technologies, new control approaches to enhance ultra-fast nonlinear frequency conversion processes, and performant techniques of nonlinear spectroscopy to detect or image samples of molecular species.
Quantum physics rules the interaction of photons with matter. This raises fundamental questions and leads to metrological applications. We analyze theoretically experiments from matter-wave physics with quantum gases in micro-gravity to laser development.
We conduct experiments in the field of laser physics and quantum optics using the laser with its almost endless possibilites.
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.
