Theoretical Quantum-Nano Photonics
Prof. Dr. Darrick Chang
- Activities:
Our research focuses on developing novel techniques to manipulate quantum interactions between light and matter, advancing theoretical tools to understand these phenomena, and proposing novel applications for such systems. Topics that we are interested in include, but are not limited to:
- Atom-nanophotonics interfaces
- Quantum optics and atomic physics
- Quantum optics using atomic arrays
- Nanoscale optical trapping techniques
- Quantum vacuum (Casimir) forces
- Optomechanics
- Graphene optics and nanomechanics
We work on a combination of fundamental and applied research in these areas, and furthermore collaborate with leading experimental groups worldwide to bring our ideas toward realization.
The group has opportunities for outstanding PhD students and postdocs. For more information, please contact This email address is being protected from spambots. You need JavaScript enabled to view it. directly. Information on application procedures can be found on the ICFO jobs website.
