Retardation effects on the Peierls phase

Research output: Contribution to journalArticlepeer-review

13 Scopus citations


The mean field theory of the Peierls instability is extended to include the small momentum transfer interaction, which is shown to be a retarded interaction. The Peierls transition temperature is shown to depend significantly on the bare phonon frequency. A positive isotope shift parameter is predicted, with values in the range 0-0.5. It is also argued that the ratio of the zero temperature gap to the transition temperature is larger than the BCS value of 3.5.
