DOI: 10.1103/physrevlett.133.146502
Abstract: We develop a theory that explains the low-energy optical excitations near 1.5 eV observed by optical experiments in NiPS_{3}. Using ab initio methods, we construct a two-band Hubbard model for two effective Ni orbitals. The dominant effective… read more here.
