- 論文の詳細を見る
Spin density wave (SDW) state at quarter-filling has been examined for two-coupled chains with interchain coupling which is given by a Coulomb repulsion acting on 4k_F charge density waves with k_F being the Fermi wave number. In terms of the transfer integral method, we study a transverse incommensurability induced by a phase difference 6 (a misfit) between two chains. The competition between the interchain commensurability energy and the interchain interaction, which leads to a crossover from the commensurate state to the incommensurate state, has been demonstrated by evaluating the renormalized interchain phase difference, the probability distribution function of the phase and the correlation of density waves.
