## Description

- description: Ascertaining and controlling dephasing of optical transitions in solids
    is of paramount importance for optoelectronic applications and fundamental considerations
    in the condensed matter optics. We here perform coherent nonlinear spectroscopy
    of a charge-tunable transition metal dichalcogenide monolayer. We demonstrate
    that homogeneous linewidth and population decay of exciton complexes hosted by
    these materials can be directly tuned, by at least an order of magnitude, by the
    applied gate voltage, governing the free carrier density and the Fermi level.
    By performing two-dimensional spectroscopy, we also show that the same functionality
    permits to control quantum coherent coupling between different exciton species.
