(abstract)

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.
