Query: Tunable Feshbach resonances and their spectral signatures in bilayer
  semiconductors   Feshbach resonances are an invaluable tool in atomic physics, enabling
precise control of interactions and the preparation of complex quantum phases
of matter. Here, we theoretically analyze a solid-state analogue of a Feshbach
resonance in two dimensional semiconductor heterostructures. In the presence of
inter-layer electron tunneling, the scattering of excitons and electrons
occupying different layers can be resonantly enhanced by tuning an applied
electric field. The emergence of an inter-layer Feshbach molecule modifies the
optical excitation spectrum, and can be understood in terms of Fermi polaron
formation. We discuss potential implications for the realization of correlated
Bose-Fermi mixtures in bilayer semiconductors.
