## Description

- description: We report the experimental observation of quadrupolar exciton states
    in the reflectance contrast spectrum of 2H-stacked bilayer MoSe2. The application
    of a vertical electric field results in a quadratic energy redshift of these quadrupolar
    excitons, in contrast to the linear energy splitting observed in the coexisting
    dipolar excitons within the bilayer MoSe2. We perform helicity-resolved reflectance
    contrast measurements to investigate the spin and valley configurations of the
    quadrupolar exciton states as a function of applied vertical electric and magnetic
    fields. Comparing our results with a phenomenological coupled-oscillator model
    indicates that the electric- and magnetic-field dependence of the quadrupolar
    exciton states can be attributed to the intravalley and intervalley hybridization
    of spin-triplet interlayer excitons with opposite permanent dipole moments, mediated
    by interlayer hole tunneling. These results position naturally stacked MoSe2 bilayers
    as a promising platform to explore electric-field-tunable many-body exciton phenomena.
