Cartoon describes how perovskite nanocube artificial solids can be harnessed to simulate cooperative phases in the vicinity of the Mott insulator-to-metal transition. (a) Cooperative effects, such as super-radiance, emerge from long-range interactions Inline graphic when coupled via an external light field. (b) Local interactions Inline graphic govern the photoinduced transition from an exciton gas and an electron–hole liquid in a semiconductor, realizing a Mott transition that can be fully mapped onto a repulsive Hubbard model in a magnetic field h.
