## Description

- description: Moiré superlattice material has emerged as a promising platform for
    studying the correlated states in condensed matter physics. These correlated states
    have substantial effects on the emission coherence, an important parameter for
    quantum light applications. However, the effect of correlated states on the excitonic
    emission coherence is largely unexplored. Here, we show that the coherence of
    moiré interlayer exciton emission in tungsten diselenide (WSe2)/molybdenum disulfide
    (MoS2) heterobilayers is sensitive to the correlated insulating states in this
    material. We demonstrate that the emission linewidth of interlayer exciton shows
    a dip at a particular power range, which we attributed to excitonic (bosonic)
    correlation. Moreover, such linewidth minima also appear in the doping dependence
    photoluminescence spectrum at the integer electronic filling factor,f=1, demonstrating
    the effect of the electronic (fermionic) correlated insulating state on the interlayer
    exciton emission coherence. Our results demonstrate the richness of exciton-exciton
    and exciton-electron interactions in moiré semiconductors and pave the way for
    engineering emission coherence by controlling such interactions.
