Surface Plasmon Polaritons in Relation to Cold Fusion

In the period before heat generation starts in Ni-H cold fusion, photon emission or a burst of gammas is produced lending some credence to the idea that surface plasmon polaritons may be involved in initiating the reaction. I am not sure what they mean by whiskers in the following patent. Do their whiskers include the tubules in sintered nickel? It is so ambiguous, it is hard to see if covers Rossi's E-Cat, Piantelli's stimulation or my hypothetical idea about a metastable graphane state and using nickel nanotubes.  Lawyers do not comprehend enough physics to make sense out of patents in any case. I wonder how NASA figured out the significance of carbon.  Do they have secret experiments, industrial espionage or are they just guessing? The moral to the story: It is easy to make a proton from a neutron, but getting a neutron from a proton is another matter!

When light interacts with metal surfaces, it excites electrons, which can form propagating excitation waves called surface plasmon polaritons. These collective electronic excitations can produce strong electric fields localized to subwavelength distance scales1, which makes surface plasmon polaritons interesting for several applications. Many of these potential uses, and in particular those related to quantum networks2, require a deep understanding of the fundamental quantum properties of surface plasmon polaritons. Remarkably, these collective electron states preserve many key quantum mechanical properties of the photons used to excite them, including entanglement3, 4 and sub-Poissonian statistics5. Here, we show that a single-photon source coupled to a silver nanowire excites single surface plasmon polaritons that exhibit both wave and particle properties, similar to those of single photons. Furthermore, the detailed analysis of the spectral interference pattern provides a new method to characterize the dimensions of metallic waveguides with nanometre accuracy.
