SUMMARY
The discussion centers on the concept of monopolar polarization in highly asymmetric crystals, as introduced in the article from Physical Review B. The author challenges the traditional view that polarization is solely dipolar, highlighting that monopole polarization can exist due to the arrangement of point charges and dipoles within the crystal's elementary cell. This model accounts for indirect interactions among point charges through a polarized lattice, which does not contradict the multipole expansion theory when considering multiple points within a single cell.
