This paper seeks to synthesize much recent work on the cuprate high-temperature superconductors around the latest energy-resolved scanning tunnelling microscopy (STM) results from Davis and co-workers. The STM conductance diffuse scattering results in particular are employed as point of entry to discuss bosonic modes, of both condensed and uncondensed form. The bosonic mode picture is essential to understanding an ever-growing range of observations within the high-temperature superconductivity field (HTSC). The work is expounded within the context of the site-inhomogeneous negative-U boson–fermion modelling long advocated by the present author. This general approach is at present seeing much theoretical development, into which I have looked to couple many of the experimental advances. While this formal theory is not yet sufficiently detailed to cover adequately all the experimental complexities presented by the real cuprate systems, it is clear that it affords very appreciable support to the line taken. An attempt is made throughout to clarify why and how it is that these novel circumstances and phenomena are tied so very closely to this particular set of materials.
