概要
- 論文の詳細を見る
The ground state and collective modes of' spin density wave (SDW) states with a quarterfilled band are examined in the presence of a two-f'old periodic potential which originates inthe anion lattice of organic conductors, The competition between the potential, 11/O, and thecommensurability energy results in the coexistence of the 2A:p-SDW and the 4Ap-CDW (chargedensity wave) and the reduction of an excitation gap for the longitudinal mode. The IV'g-dependence of the gap is examined in terms of a phase Hamiltonian.
