... fusion. Clearly, this raises fundamental questions because the probability of a d-d fusion, under the conditions of the FPE cell, is extremely small. As stated in ref. [1], “it is necessary to reconsider the quantum mechanics of electrons and deuterons in such host lattices.” The goal of this paper ...

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.
