  The self-organized dopant percolative filamentary model, entirely orbital in
character (no spins), explains the evolution with doping of Fermi arcs observed
by ARPES, including the abrupt transitions in quasiparticle strength observed
near optimal doping in cuprate high temperature superconductors. Similarly
abrupt transitions are also observed in time-resolved picosecond relaxation
spectroscopy at 1.5 eV, and these are explained as well, using no new
assumptions and no adjustable parameters. The anomalous "precursive"
temperature-dependent strains observed by EXAFS are associated with relaxation
of filamentary ends.
