Collective optical properties of moir\'e excitons
Collective optical properties of moir\'e excitons
We propose that excitons in moir\'e transition metal dichalcogenide bilayers offer a promising platform for investigating collective radiative properties. While some of these optical properties resemble those of cold atom arrays, moir\'e excitons extend to the deep subwavelength limit, beyond the reach of current optical lattice experiments. Remarkably, we show …
