Hybridization of interlayer excitons in bilayer semiconductor hints at many-body state

Excitons, bound states between an electron (i.e., a negatively charged particle) and a hole (i.e., the absence of an electron) in materials, are a key focus of condensed matter physics studies. These bound states can give ...
