A team of scientists from Würzburg and #Dresden has achieved a breakthrough - the first detection of excitons (electrically neutral quasiparticles) in a topological insulator. This discovery paves the way for a new generation of light-driven computer chips and quantum technologies. 🚀

Raziman also took into account that #excitons interact with each other through exciton-exciton annihilation, which normally decreases light emission at high intensities.

So he generalized the theory of Purcell enhancement to be more precise for a range of excitonic materials like #2DSemiconductors, #perovskites, #OrganicCrystals or #CarbonNanotubes.

Scientists use #nanophotonics to improve light emission. The strong electric field near nanostructures can excite molecules and extract light from them more efficiently, creating better light sources. We usually model this by assuming that the emitter stays fixed. But in many practical materials, emitting #excitons move around! We found a recipe for making such devices better by figuring out how to do calculations more correctly (led by @albertogcurto): https://onlinelibrary.wiley.com/doi/10.1002/adom.202200103
