Title:Models for nuclear fusion in the solid state

Abstract:This article presents a theoretical framework for enhancing nuclear fusion rates in solid-state environments under near-ambient conditions. Drawing on quantum tunneling, electron screening, and resonance energy transfer, the study proposes rate enhancements of more than 40 orders of magnitude for deuterium-deuterium (D-D) fusion in palladium lattices. A generalized nuclear Dicke model describes a fusion-fission process as a result of energy transfer between D-D and palladium mediated by lattice vibrations. Practical challenges such as decoherence, destructive interference, receiver decay, and achieving resonance between donor and receiver systems are addressed. Experimental strategies to validate the model are proposed along with its implications for the advancement of solid-state fusion as a potential pathway to sustainable energy technologies.
