#Chirality of #BioMolecules (left/right-handedness) is central to life. Light can be chiral too, a tool to interact with them. Light can also excite spins in #2dSemiconductors and rotate objects. #Nanophotonics can enhance these very weak effects. We surprisingly found that different phenomena, all relying on chirality of light, are incompatible! And found design rules for #metasurfaces for enhancing different chiral interactions (led by @albertogcurto).

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.
