Peierls instability and paraconductivity in Pseudo-one-dimensional conductors

e effects of ~ on the Peierls Instability, the Kohn Anomalies and the Fluctuation Conductivity in Pseudo-One-dimensional conductors, where~ denotes the Fermi energy as measured from the middle of the conduction band. In a tight-binding model, ~= -W cos kFd where 2W is the bandwidth and d is the interatomic distance. ~ is a measure of the deviation from half-filledness since~ vanishes for exactly half-filled conduction
