Welcome! This is the home page for the theory division at the Max Planck Institute for the Science of Light (MPL). The division is led by Florian Marquardt. We are exploring all aspects of the coupling between light and matter.
Christmas Lecture [December 2017]
As the festive season approaches, we are getting ready for this year’s Christmas lecture at the FAU Erlangen-Nuremberg. We are looking forward to seeing you there on 14th December!
Light and Motion in a Helium Drop [August 2017]
What happens when you combine the physics of superfluid helium with optomechanics, in a levitated drop that has optical whispering gallery modes of outstanding quality? In our most recent work, we are analyzing all the basic aspects of such a system, to lay the groundwork for an upcoming experiment. A particular feature in this new optomechanics platform is the coupling between rotations, vibrations, and the light field. Read more in our recent manuscript or look at the slides of a talk given at the SPIE in San Diego.
OMT Summer School [July 2017]
We were pleased to welcome a group of keen young physicists to our OMT Summer School “Quantum Measurements and Theoretical Cavity Optomechanics” from 5th till 7th July here at the Max Planck Institute for the Science of Light. Please refer to our website for more information.
Cavity Optomagnonics Workshop [June 2017]
The first workshop worldwide on this new topic, coupling light to magnons, was a great success. We welcomed many important experts in the field to the new building of the MPL, and exchanged scientific viewpoints across different fields (like quantum optics, magnonics, spintronics, etc.). See the workshop website.
Snowflakes go chiral! [April 2017]
We have discovered a novel way to make sound waves go one way (and one way only). See our new paper on a topological insulator for sound waves at the nanoscale. You can also look at a brief summary of this (and other related papers of ours), in the slides from a talk at San Sebastian (July 2017).
Move into the new building! [Sept 2016]
We moved into the new MPL building end of September 2016.
We are currently looking for both PhD students as well as postdoctoral researchers. Join our team at the MPL theory division and explore the world of photons and matter!
If you are curious about new quantum technologies, come and join us in our explorations at the intersection of nanophysics and quantum optics.
Our main focus is currently in optomechanics. This new field studies the interaction of light and nanomechanical motion, down into the quantum regime. This opens the door towards quantum optomechanical circuits, many-body physics, potential applications in ultrasensitive measurements, quantum information, and fundamental tests of quantum mechanics. Further research topics include quantum electrodynamics and quantum computing in superconducting circuits, topological photonics and phononics, decoherence, and quantum transport.
Our work has both analytical and numerical components, and in most of the topics we have collaborations with experimentalists. Thus, computer skills and the desire to apply theory to realworld problems are strong advantages. We put particular emphasis on physical understanding.
We have ongoing collaborations with both experimental and theoretical groups all over the world, including at Yale, Caltech, McGill and other institutions. The payment and benefits are based on the German TVöD guidelines.
The Max Planck Society is committed to increasing the number of individuals with disabilities in its workforce and therefore encourages applications from such qualified individuals. Furthermore, the Max Planck Society seeks to increase the number of women in those areas where they are underrepresented and therefore explicitly encourages women to apply.
The set of documents you should send with your application comprises the following:
PhD applications: a CV and the names of two expert references.
PostDoc applications: a CV, a list of publications, and the names of two expert references.
We will start reviewing applications immediately but will continue to accept applications indefinitely.
