Just as electrons cease to be point particles when they are injected into a solid, deuterons cease to be point particles when they become bound to the interior of a deuteride host. Additional quantum mechanical effects, well‐known from the behavior of electrons bound within a solid state environment at low temperature, have the potential to profoundly affect the transport of deuteronic charge in a solid in a manner that runs contrary to conventional wisdom based on free space thinking. During the prolonged electrolysis of LiOD by Pd, these kinds of effects can be used to explain the associated anomalous cold fusion heating phenomenon through interplay between the highly nonequilibrium circumstances associated with overcharging PdDx beyond the value x=1 and the quantum mechanical implications that result from 1) periodic order, 2) lattice‐induced broadening of deuteronic charge, and 3) the large lattice strain energies that result when individual deuterons compete for a common location. This interplay provides a means for satisfying the necessary conditions for the formation and subsequent nuclear decay of a new, chemical matter phase, which we have named Bose Bloch Condensate (BBC). The combination of overcharging and periodic order provide the ingredients for this new form of nuclear interaction, governed by new selection rules that result from known quantum mechanical effects. We have named this new form of interaction, Lattice Induced Nuclear Chemistry (LINC). In this paper, we provide an explanation of the manner in which interplay between periodic order and overcharging provide the necessary prerequisite conditions for occupation of the BBC state and the rules for subsequent interaction through LINC.
