In particular, we consider coherently coupled spin states with an external field, where only one spin component interacts with the bath, enabling light dressing of the impurity and spin-dependent bath-impurity interactions. Through detailed comparisons with ab-initio many-body simulations, we demonstrate that the composite system is accurately described by a simplified effective Hamiltonian. The latter builds upon previously developed effective potential approaches in the absence of light dressing. It can be used to extract the impurity energy, residue, effective mass, and anharmonicity induced by the phononic dressing. Light-dressing is shown to increase the polaron residue, undressing the impurity from phononic excitations because of strong spin coupling. For strong repulsions, previously shown to trigger dynamical Bose polaron decay (a phenomenon called temporal orthogonality catastrophe), it is explained that strong light-dressing stabilizes a repulsive polaron-dressed state. Our results establish the effective Hamiltonian framework as a powerful tool for exploring strongly interacting polaronic systems and corroborating forthcoming experimental realizations.","lang":"eng"}],"license":"https://creativecommons.org/licenses/by/4.0/","month":"10","title":"Competition of light-and phonon-dressing in microwave-dressed Bose polarons","has_accepted_license":"1","publication_identifier":{"eissn":["2542-4653"]},"file":[{"file_id":"20673","creator":"dernst","file_name":"2025_SciPostPhys_Koutentakis.pdf","file_size":1725787,"success":1,"date_created":"2025-11-24T08:42:42Z","checksum":"04d0e47ba66c63737431d7b8ed1df4bc","date_updated":"2025-11-24T08:42:42Z","access_level":"open_access","relation":"main_file","content_type":"application/pdf"}],"citation":{"ama":"Koutentakis G, Mistakidis SI, Grusdt F, Sadeghpour HR, Schmelcher P.
