Query: Application of an Extended Eliashberg Theory to High-T_c Cuprates   In recent years a unified phenomenological picture for the hole doped
high-T_c cuprates has emerged for a spin and charge spectroscopy. Spectral
anomalies have been interpreted as evidence of charge carrier coupling to a
collective spin excitation present in the optical conductivity, in ARPES
(angular resolved photoemission), and in tunneling data. These anomalies can be
used to derive an approximate picture of a charge carrier-exchange boson
interaction spectral density I^2 chi(omega) which is then be used within an
extended Eliashberg formalism to analyze normal and superconducting properties
of optimally doped and overdoped cuprates. This paper reviews recent
developments and demonstrates the sometimes astonishing agreement between
experiment and theoretical prediction.
