Description
A comprehensive understanding of electron–photon correlation is essential for describing the reshaping of the electronic ground state of molecular systems embedded in quantum electrodynamics (QED) environments. The strong-coupling QED Hartree–Fock (SC-QED-HF) theory addresses these aspects by providing a consistent molecular orbital framework in the strong coupling regime. However, in experimental realizations, light–matter coupling is constrained by the quantization volume of the optical cavity or photonic device. It has been suggested that pumping a cavity with quantum light, such as a laser field, may enhance the effective light–matter coupling by driving the system into a non-equilibrium state with modified properties, including altered intermolecular interactions. In this work, we develop an extension of the SC-QED-HF model that constrains the parameters describing frequency dispersion to a fixed number of photons, enabling a systematic investigation of these effects. Our results suggest that cavity pumping provides a novel route to indirectly enhance light–matter coupling through amplified interactions with quantum fields.
