Many investigators on the other hand, who are of the opinion that quantum mechanics precludes transitions of this kind having any ontological status, interpret the transitions as measurement-induced, or as characterizing our knowledge of the atom rather than the atom itself.

... The energy of the particle is less than the potential barrier it enters, E < V0 . It is therefore certain that the particle cannot continue as a propagating wave into the barrier. The reflection probability must therefore be equal to one, R = |r|2 = 1. From their definitions, k and κ are real number ...

However, there are some points that we still can make: Electrons at (or close to) the Brillouin zone in each band are diffracted and form standing waves, i.e. the ...

Tight binding

In solid-state physics, the tight-binding model (or TB model) is an approach to the calculation of electronic band structure using an approximate set of wave functions based upon superposition of wave functions for isolated atoms located at each atomic site. The method is closely related to the LCAO method used in chemistry. Tight-binding models are applied to a wide variety of solids. The model gives good qualitative results in many cases and can be combined with other models that give better results where the tight-binding model fails. Though the tight-binding model is a one-electron model, the model also provides a basis for more advanced calculations like the calculation of surface states and application to various kinds of many-body problem and quasiparticle calculations.
