## Description

- description: Transition metal dichalcogenide moiré superlattices host rich correlated
    electronic states with high tunability. Their integration with optical cavities
    offers a new platform to explore hybrid light–matter interactions. However, the
    interplay between electron correlations and polariton formation remains uncharted.
    Here, we demonstrate the realization of a Mott insulator polariton in a gate-tunable
    MoSe2/WS2 moiré heterostructure embedded in a microcavity at the moiré lattice
    filling of ν = 1. A silver top layer was used to gate the moiré lattice and form
    the cavity reflection layer. Magnetic field studies indicate that the polaritons
    inherit valley Zeeman splitting from the moiré excitons, exhibiting saturation
    behavior similar to that of the bare moiré excitons. Our work establishes moiré
    polaritons as an electrically and magnetically tunable platform for engineering
    the quantum phases of light and matter.
