Abstract

Electronic states of an e_g electron are calculated in the system composed of two MnO ₆ octahedra with the inclusion of the Berry phase acquired by parallel transport. Based on this calculation, a comment is made on the controversy between "Wigner-crystal" and "paired-stripe" models for the the insulatIng charge-ordered manganese oxides.
