You are right; there must be an additive magnetic concentration process in play.
The hot spot is the big phenomena in Nanoplasmonic. It will be created in a collection of nanoparticles surrounded by a dielectric medium. This is known science and does not require more proof. The hot spot is just a nanometer or two in diameter. However, it exists in a global BEC environment. The large magnetic field may be a result of an entanglement process where all the hotspots act as if they are coming from a single huge super atom. That is, a hot spot projects the entire magnetic product of all the hotspots as an additive superposition of the entire global BEC. All the magnetic and electrostatic power of all the many billions of hotspots are concentrated quantum mechanically into one just one hotspot until it disrupts a close by nucleus. When that disruption happens, binding energy from the nucleus is distributed throughout the BEC. Almost instantaneously after BEC QM decoherence, the global BEC is rebuilt until the next nuclear reaction occurs. Magnetic QM concentration is just the reverse of gamma thermalization. It is as if the entire core of the Ni/H reactor is made of a huge single atom.
