• 論文の詳細を見る

• The electronic properties of quarter-filled organic materials showing spin-Peierls transition are investigated theoretically. By studying the one-dimensional extended Peierls-Hubhard model analytically as well as numerically, we find that there is a competition between two different spin-Peicrls stales due to the tetramized lattice distortion in the strongly correlated regime. One is accompanied by latticed imerization which can be interpreted as a spontaneous Molt insulator, while the other shows the existence of charge order of Wigner crystal-type. Results of numerical density matrix renormalization group computations on sufficiently large system sixes show that the latter is stabilized in the ground state when both the on-site and the inter-site Coulomb interactions are large.
