## Description

- description: Interactions between out-of-plane dipoles in bosonic gases enable the
    long-range propagation of excitons. The lack of direct control over collective
    dipolar properties has hitherto limited the degrees of tunability and the microscopic
    understanding of exciton transport. In this work, we modulate the layer hybridization
    and interplay between many-body interactions of excitons in a van der Waals heterostructure
    with an applied vertical electric field. By performing spatiotemporally resolved
    measurements supported by microscopic theory, we uncover the dipole-dependent
    properties and transport of excitons with different degrees of hybridization.
    Moreover, we find constant emission quantum yields of the transporting species
    as a function of excitation power with dominating radiative decay mechanisms over
    nonradiative ones, a fundamental requirement for efficient excitonic devices.
    Our findings provide a complete picture of the many-body effects in the transport
    of dilute exciton gases and have crucial implications for the study of emerging
    states of matter, such as Bose-Einstein condensation, as well as for optoelectronic
    applications based on exciton propagation.
