19 Jan 2007 | | Journal: | Phys. Rev. B75, 020508 (2007) | | Subject: | Superconductivity; Strongly Correlated Electrons | | Abstract: | We discuss the characteristic effects of the electron plasmon interaction resulting from the ~ 1 eV plasmon, which is a universal feature in the cuprates. Using the framework of a one-band tight binding model, we identify signatures of this low energy plasmon in the electronic structure of metallic overdoped Bi2212 as well as half-filled insulating SCOC. The electron-plasmon interaction is found to yield renormalizations near the Fermi energy in reasonable accord with experimental observations, and to produce dispersion anomalies at higher energies. | | Source: | arXiv, cond-mat/0701465 | | Services: | Forum | Review | PDF | Favorites | |
