If a cavity changes electron-phonon coupling, then it changes the screening energy

Ce qu'elle propose

Two settled facts have never been put in the same room. First: an unpowered resonator placed near a superconductor changes its transition temperature, and first-principles calculations trace the effect to the vacuum field reshuffling how electrons trade energy with lattice vibrations. Second: the rate at which two nuclei fuse inside a metal depends on the screening energy of the electrons around them, a quantity that varies by more than a factor of twenty between hosts and is directly measurable on an accelerator. If a cavity can reshuffle the electron-phonon interaction in a solid, then a cavity around a hydrogen-loaded lattice should move the screening energy — and therefore the fusion rate — in that lattice. If the electromagnetic vacuum around a loaded metal is reshaped, then the screening energy measured in that metal changes. That is the vacuum-catalysed fusion hypothesis reduced to an experiment with two known instruments, and it is, as far as this library shows, unstated anywhere.

Why the library suggests it

The cavity effect is measured by three independent groups, with the shift tracking the simulated field map along a single flake, going to zero outside the resonator, and reversing sign when the antenna is detuned below resonance (Cavity-enhanced superconductivity in the two-dimensional limit of NbSe2, 2026; Evidence for vacuum-enhanced superconductivity in NbSe2, 2026; Cavity-enhanced superconducting response in an underdoped cuprate, 2026). The screening energy is measured on an accelerator, host by host: about 27 electronvolts in titanium, about 310 in palladium, about 600 in palladium oxide, with a hundredfold rate difference at 2.5 kiloelectronvolts of bombarding energy (Screening energy for low energy nuclear reactions in condensed matter, 2020). The mechanism linking conduction-electron density to reaction rate, with the reaction-rate gain calculated at up to twenty orders of magnitude below 10 keV, is Electron Screened and Enhanced Nuclear Reactions (2022), and the reactions themselves are on the record with a NASA byline (Novel nuclear reactions in bremsstrahlung-irradiated deuterated metals, 2020).

The experiment or build

Take Kasagi's accelerator screening measurement exactly as published and add one component: a terahertz split-ring or antenna resonator around the target, unpowered, tuned to the target's own phonon band. Measure the screening energy with the resonator on resonance, detuned, and absent, in one session, on the same target. The settling measurement is the screening energy in electronvolts, measured the standard way, as a function of cavity detuning — with the shift going to zero off resonance and outside the mode volume, exactly as the superconducting version does. No new physics has to be assumed for this experiment to be worth doing; if the shift is zero the result bounds the coupling, and if it is not, it is the most important measurement in this programme.

Où elle en est

What to watch — both halves are published and peer-reviewed, and the combination has never been attempted.

L'ingénieur qu'elle forme: Nuclear physicists and terahertz photonics engineers in the same room — that combination barely exists yet, which is exactly why the test has not been run.
