摘要: Effects of the long range Coulomb interaction and distribution Br atoms are investigated on charge density wave KCP in connection with experimental finding correlation length along chain, ξ, even at relatively high temperatures. It is shown that increase ξ appreciably, though data indicates longer than theoretical estimate. In order to explain experiment it is, then, argued based work Kondo Yamaji - has large 4 k F -component, which leads commensurability pinning CDW through higher harmonics. This argument qualitatively explains phonon gap frequency low
