TLDR
In this article, it was shown that the spin-singlet in the quarter-filled band is necessarily charge-disproportionated, with charge-rich pairs of nearest neighbor sites separated by charge-poor pairs of sites in the insulating state.About:

Valence transition model of the pseudogap, charge order, and superconductivity in electron-doped and hole-doped copper oxides
TL;DR: In this article, a valence transition model for electron-and hole-doped cuprates is presented, within which there occurs a discrete jump in ionicity in both families upon doping, at or near optimal doping in the conventionally prepared electron doped compounds and at the pseudogap phase transition in the hole doped materials.

Possible high Tc superconductivity in the Ba-La-Cu-O system
TL;DR: In this paper, Ba−La−Cu−O system, with the composition BaxLa5−xCu5O5(3−y) have been prepared in polycrystalline form, and samples with x=1 and 0.75,y>0, annealed below 900°C under reducing conditions, consist of three phases, one of them a perovskite-like mixed-valent copper compound.

The resonating valence bond state in La2CuO4 and superconductivity
TL;DR: The oxide superconductors, particularly those recently discovered that are based on La2CuO4, have a set of peculiarities that suggest a common, unique mechanism: they tend in every case to occur near a metal-insulator transition into an odd-electron insulator with peculiar magnetic properties.

Studies of polaron motion: Part I. The molecular-crystal model
TL;DR: In this paper, a model for polaron motion is described, in simplified form, incorporating the principal physical features of the problem, and the conditions under which the size of the polaron becomes comparable to a lattice spacing (small) are discussed.

Resonating valence bonds: A new kind of insulator?
TL;DR: In this article, the possibility of a new kind of electronic state corresponding roughly to Pauling's idea of resonance valence bonds in metals was pointed out, and an estimate of its energy was made in one case.
