Coexistent States of Charge Density Wave and Spin Density Wave in One-Dimensional Systems with the Inter-site Coulomb Interaction under the Electron Filling Control

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/16370The coexistent state of the spin density wave (SDW) and the charge density wave (CDW) in the one-dimensional systems is studied by the mean field approximation at T=0 in various electron-filling cases. We find that the coexistent state of SDW and CDW is stabilized when the on-site and the inter-site Coulomb interactions have the values estimated for the organic conductors. The ground state energies have cusp-like minima at 1/4, 3/8, 5/12, 7/16, 7/20 and 9/20-fillings.5 pages, 7 figuresStrongly Correlated ElectronsCoexistent States of Charge Density Wave and Spin Density Wave in One-Dimensional Systems with the Inter-site Coulomb Interaction under the Electron Filling Controltext
