My indication that electrons who have had their charge removed through fractionalization and photon entanglement can be packed into a small volume comes from the experimentally verified power density of 1,000,000,000,000,000 watts per cm2 that has been measured in nanoplasmonuc hot spots.
The NiH reactor has improvements in hot spot formation technology that can increase this power density by about 6 orders of magnitude. Such improvements are the use of nickel as the metal substrate, the compound 5 micron blackbody resonant nickel particle with nanowire hair and the use of pressurized hydrogen as the plasmonic dielectric. I assume these improvements take the power density in the hot spot to 10^^20 watts/cm2. Assuming that the voltage inside the hot spot in minimal since confinement is easily achieved, the amperage carried by a nanometer sized volume of the hot spot must be in the 100,000 amps range at a minimum or perhaps far more. This is the amperage range carried by a top end lightning bolt. The polaritons are all entangled and coherent since they form a soliton within a nano-vortex at or near the 1 dimensional nanowire heads which serves to fractionalize the electrons in the dipoles formed on the surface of the micro particle thereby replacing the charge of the electron through quantum mechanical tunneling. This large circulating current is the source of the magnetic field that is the most powerful EMF source produced in the universe at 10^^16 tesla. It is this magnetic field that disrupts the vacuum and catalyzes nuclear reactions through the formation of real pions through the breakdown of the vacuum. Polaritons have nothing to do with helium or any other form of matter. If you are interested in black hole research, I have just read how to do it with polaritons. You can produce worm holes, white holes, and black holes, even alternate universes, http://arxiv.org/pdf/1104.3013v2.pdf Black Holes and Wormholes in spinor polariton condensates Once a polariton goes into a hot spot, it cannot come out. > >
