Framework for Understanding LENR Processes, Using Ordinary Condensed Matter Physics

As I have emphasized\footnote{\urllink{S.R. Chubb, Proc. ICCF10 (in press). Also, http://www.lenr-canr.org/acrobat/ChubbSRnutsandbol.pdf} {http://www.lenr-canr.org/acrobat/ChubbSRnutsandbol.pdf}, S.R. Chubb, Trans. Amer. Nuc. Soc. 88 , 618 (2003).}, in discussions of Low Energy Nuclear Reactions(LENRs), mainstream many-body physics ideas have been largely ignored. A key point is that in condensed matter, delocalized, wave-like effects can allow large amounts of momentum to be transferred instantly to distant locations, without any particular particle (or particles) acquiring high velocity through a Broken Gauge Symmetry. Explicit features in the electronic structure explain how this can occur$^1$ in finite size PdD crystals, with real boundaries. The essential physics$^1$ can be related to standard many-body techniques\footnote{Burke,P.G. and K.A. Berrington, \underline{Atomic} \underline{and} \underline{Molecular} \underline{Processes:}\underline{an} \underline{R matrix} \underline{Approach} (Bristol: IOP Publishing, 1993).}. In the paper, I examine this relationship, the relationship of the theory$^1$ to other LENR theories, and the importance of certain features (for example, boundaries$^1$) that are not included in the other LENR theories.
