## Description

- description: Extended efforts have been devoted to the study of strongly-interacting
    excitons and their dynamics, towards macroscopic quantum states of matter such
    as Bose-Einstein condensates of excitons and polaritons. Momentum-direct layer-hybridized
    excitons in transition metal dichalcogenides have attracted considerable attention
    due to their high oscillator strength and dipolar nature. However, the tunability
    of their interactions and dynamics remains unexplored. Here, we achieve an unprecedented
    control over the nonlinear properties of dipolar layer-hybridized excitons in
    an electrically gated van der Waals homobilayer monitored by transient optical
    spectroscopy. By applying a vertical electric field, we reveal strong Coulomb
    interactions of dipolar hybrid excitons, leading to opposite density-dependent
    energy shifts of the two main hybrid species based on their dipolar orientation,
    together with a strongly enhanced optical saturation of their absorption. Furthermore,
    by electrically tuning the interlayer tunneling between the hybridized carriers,
    we significantly extend the formation time of hybrid excitons, while simultaneously
    increasing their decay times. Our findings have implications for the search on
    quantum blockade and condensation of excitons and dipolaritons in two-dimensional
    materials.
