摘要: Numerical calculations for an incommensurate phase in the Peierls instability are carried out at zero temperature by taking account of a sufficiently large number electronic states coupled potential lattice displacement and treating effect third fifth harmonics self-consistently. Total energy system, amplitudes harmonies pattern calculated changing deviation from half-occupancy conduction band. The is found to be essentially important close neighbor-hood half-filled case. results extrapolated case satisfactorily consistent with our analytic preceding paper.
