We validate the newly implemented model by showcasing the mitigation of electron spill-out when using the modified interaction tensor T mod and its derivatives for QM/MM subsystem electrostatic interactions. We continue with some tests of dimeric systems, in which one monomer is described at the QM (PW KS-DFT) and the other on the MM (AMOEBA) level of theory, interacting via a fully-polarizable embedding scheme. When varying the covalent radii that determine the damping function, we identify the magnitude of errors between the different QM/MM energy components. Subsequently, the polarizable QM/MM model is tested on realistic solute-solvent systems, where we compute the molecular dipole moment of the embedded molecule.
