New Approach to the Theory of Superexchange Interactions
TL;DR: In this article, the theory of indirect exchange in poor conductors is examined from a new viewpoint in which the $d$ (or $f$) shell electrons are placed in wave functions assumed to be exact solutions of the problem of a single $d-electron in the presence of the full diamagnetic lattice.

Simple Model for Semiconductor-Metal Transitions: Sm B 6 and Transition-Metal Oxides
L. M. Falicov,J. C. Kimball +1 more
TL;DR: In this paper, a simple model for a semiconductor-metal transition, based on the existence of both localized (ionic) and band (Bloch) states, was proposed, which differs from other theories in that we assume the one-electron states to be essentially unchanged by the transition.

Charge modulations in La2-xSrxNiO4+y: Ordering of polarons.
TL;DR: Electron diffraction of La 2-x Sr x NiO 4+y (0≤x≤I) reveals at low temperatures the presence of sharp, quasi-2D superlattice peaks around the (π,π) point, which can be understood in terms of the ordering of polarons.

A Lattice Model of Liquid Helium, II
TL;DR: In this paper, the authors used a rather direct method of approximation without referring to the spin system for calculating the partition function of the lattice model, and tried to understand qualitatively the thermodynamical behavior of liquid helium.

Missing valence states, diamagnetic insulators, and superconductors
TL;DR: A model with such interactions as well as interatomic repulsions gives insulating behavior near half-filling and superconductivity farther from it, in agreement with the properties of BaPb/sub x/Bi/sub 1-//sub X/O/sub 3/ and Ba/ sub x/K/sub 4/.
