Clearly, it is important to investigate how the unphysical polarization at the outer boundary affects the properties of the central quantum subsystem. To our knowledge, using the minimum-image convention (MIC) in fully self-consistent PE approaches has not yet been explored for this purpose. The effects of long-range electrostatic interactions have mainly been investigated for electrostatic embedding QM/MM schemes. Kratz et al. developed a polarizable QM/MM approach with long-range electrostatic corrections (LREC) using a combination of the MIC and a switching and smoothing function. Boulanger and Thiel proposed to use solvent boundary potentials to include long-range effects in polarizable QM/MM based on the Drude oscillator model. Others have used continuum models to include bulk solvent effects in PE based on induced dipoles and fluctuating charges. In this work, we address the unphysical polarization by introducing the MIC in the self-consistent solution of induced dipoles in a fully self-consistent PE model. The PE-MIC model is implemented in the Polarizable Embedding library (PElib) interfaced to the Dalton program. Using PE-MIC, the performance of standard PE using cutoff/droplet models is investigated in terms of induced dipoles and associated electrostatic potentials for different chromophores embedded in homogenous aqueous solutions and inhomogenous biomolecular environments. Moreover, the effects on excitation energies, oscillator strengths, and two-photon absorption (TPA) cross-sections are evaluated.
