What makes LENR so complicated: The polariton can be formed out of many and varied particles through entanglement: A polariton is the result of the mixing of a photon <https://en.wikipedia.org/wiki/Photon> with a polar excitation in a material. The following are types of polaritons: - Phonon polaritons <https://en.wikipedia.org/w/index.php?title=Phonon_polaritons&action=edit&redlink=1> result from coupling of an infrared <https://en.wikipedia.org/wiki/Infrared> photon with an optical phonon <https://en.wikipedia.org/wiki/Phonon>; - Exciton polaritons <https://en.wikipedia.org/wiki/Exciton-polaritons> result from coupling of visible light <https://en.wikipedia.org/wiki/Visible_light> with an exciton <https://en.wikipedia.org/wiki/Exciton>; - Intersubband polaritons <https://en.wikipedia.org/wiki/Intersubband_polariton> result from coupling of an infrared <https://en.wikipedia.org/wiki/Infrared> or terahertz <https://en.wikipedia.org/wiki/Terahertz_radiation> photon with an intersubband excitation <https://en.wikipedia.org/w/index.php?title=Intersubband_excitation&action=edit&redlink=1> ; - Surface plasmon polaritons <https://en.wikipedia.org/wiki/Surface_plasmon_polaritons> result from coupling of surface plasmons <https://en.wikipedia.org/wiki/Surface_plasmon> with light (the wavelength depends on the substance and its geometry); - Bragg polaritons ("Braggoritons") result from coupling of Bragg photon modes <https://en.wikipedia.org/wiki/Photonic_crystal> with bulk excitons <https://en.wikipedia.org/wiki/Exciton>;[10] <https://en.wikipedia.org/wiki/Polariton#cite_note-eradat-10> - Plexcitons <https://en.wikipedia.org/wiki/Plexciton> result from coupling plasmons <https://en.wikipedia.org/wiki/Plasmon> with excitons; [11] <https://en.wikipedia.org/wiki/Polariton#cite_note-11> - Magnon polaritons result from coupling of magnon <https://en.wikipedia.org/wiki/Magnon> with light; - Cavity polaritons.[12] <https://en.wikipedia.org/wiki/Polariton#cite_note-12> On Mon, Jul 29, 2019 at 3:02 AM Axil Axil <[email protected]> wrote: > > https://physicsworld.com/a/calculations-provide-insight-into-why-sound-waves-carry-negative-mass/ > > > Calculations provide insight into why sound waves carry ‘negative mass’ > > Its the phonons that carry negative mass.
