Conduction in non-crystalline systems

Abstract A summary is given of what is now known about the existence of localized states for electrons in three-dimensional disordered systems, and what can be conjectured about...

On the Theory of Excitation by Collision with Heavy Particles

1. It has been shown, in a well-known paper by Born and Oppenheimer, that in evaluating the energy levels of a molecule, the nuclei may be treated as fixed, or slowly vibrating,...

The Mechanical Properties of Metals

A description is given of edge and screw dislocations in a close-packed cubic lattice, which leads up to an account of the theory of Frank and Read of the origin of slip bands. ...

The Basis of the Electron Theory of Metals, with Special Reference to the Transition Metals

It is shown that the collective electron and London-Heitler models are not to be regarded as different approximations to the same exact wave function for solids in which, accord...

Bipolarons

Cooperative properties of self-localized carriers on a lattice are discussed and reviewed at a fairly basic level with an emphasis on developments of the strong-coupling theory ...
