Twisted Cavity Is a One-Way Light Path
The monopole (aka anisotropic) magnetic beam produced by spin polarization is the key to the LENR reaction. The spin can be produced by polaritons or atoms as in this experiment. Besides producing a monopole magnetic field, spin polarization also generates a change of state in time symmetry where light energy is forced to flow only in one direction. This one way flow of energy is what allows the soliton (AKA EVO) to accumulate gamma energy and down convert that energy into light and heat.
