- Abstract summary: Moir'e excitons promise a new platform with which to generate and manipulate hybrid quantum phases of light and matter.
We show that the steady states exhibit a rich phase diagram with pronounced bi-stabilities governed by multi-photon resonances.
In the presence of an incoherent pumping of excitons we find that the system can realise one- and multi-photon lasers.

- Abstract: Moir\'e excitons promise a new platform with which to generate and manipulate
hybrid quantum phases of light and matter in unprecedented regimes of
interaction strength. We explore the properties in this regime, through studies
of a Bose-Hubbard model of excitons coupled to cavity photons. We show that the
steady states exhibit a rich phase diagram with pronounced bi-stabilities
governed by multi-photon resonances reflecting the strong inter-exciton
interactions. In the presence of an incoherent pumping of excitons we find that
the system can realise one- and multi-photon lasers.

Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement.
We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.
