Welcome to the website of the Theory Division

The MPL Theory Division, led by Florian Marquardt, deals with both the quantum and classical dynamics of systems relevant for modern optics research, especially at the interface between nanophysics and quantum optics. Topics include the theory of optomechanics, neural networks and machine learning for physics, quantum optics in superconducting circuits, transport in photonic systems, fundamental questions of quantum many-body theory, nonequilibrium nonlinear dynamics, and decoherence. The group applies a variety of approaches, ranging from analytical studies to numerical simulations.

In our research, we apply tools from condensed matter theory and from quantum optics to a range of questions at the interface of nanophysics and quantum optics, addressing both quantum and classical dynamics. In our approach, we often try to identify the salient features of experimentally relevant situations and condense them into minimalist models which can then be attacked with all the state-of-the-art theoretical tools. At the same time, we also care about the direct contact with experiments, down to designing the classical electromagnetic and acoustic properties of specific structures.
