2D and quantum materials for topological and quantum nanophotonics

Due to the unique characteristics of graphene, light can be squeezed into extremely small volumes and thus facilitate strongly enhanced light-matter interactions. In addition, the plasmon wavelength can be tuned and plasmon propagation can even be switched on and off in-situ, simply by tuning the carrier density by electrostatic gates. The capability of trapping light in very small volumes could give rise to a new methods of strong interactions between light and matter, potentially unveiling new states of matter.

We have access to a both room-temperature and low-temperature near-field imaging microscopes for infared and terahertz frequencies.
