Description
Recently, we have discovered a fundamental theoretical link between the seemingly unrelated fields of polaritonic chemistry and spin glasses. Our mapping reveals a cavity‑induced spin‑glass phase of intermolecular electron correlations, which could provide the long‑sought seed for significant local chemical modifications under collective VSC. This spin‑glass mapping not only demonstrates the relevance of moving beyond the dilute‑gas approximation—where the Pauli principle becomes essential—but also suggests the existence of a phase transition in the intermolecular electron correlations. Our theoretical predictions find experimental support in recently observed Rayleigh‑scattering phase transitions under collective VSC. Finally, we explore potential implications for electron correlations in solids.
