From: Bob Cook * * I agree with you that only bosons form Bose Einstein Condensates (BEC). I am merely pointing out that photons are not the only Bose particles that can form BEC’s.
To be precise, there are only two bosons which have been proved (more or less) to be possible at ambient temperatures: protons and magnons. The magnon is a quasiparticle but there are papers demonstrating the condensation of magnons. These two particles are also associated with LENR, along with deuterons, and possibly hydrogen. Deuterium, as an atomic species or as D2, is not a boson - but as a nucleus (with no electron), it is bosonic. H2 is not a boson as it is molecular. Cooper pairs of protons are technically not bosons, since molecules and pairs of nuclei do not qualify as “composite bosons” (see the google entry). However, there is one paper (an outlier) which suggests that Cooper pairs of protons would qualify in some situations, since even though they are not bound as a single particle any more than a molecules is, there is a dynamical process which involves crossing a quantum phase transition. See: http://www.optical-lattice.com/index.php?lattice-site=cooper-pairs Hydrogen, as a proton, is not a boson nor is any hydride; but atomic hydrogen would qualify … on paper… yet atomic hydrogen cannot be stored in any metal matrix without hydriding, so as a practical matter – if we want to invoke the BEC as part of LENR, we have ONLY these 3 particles to play with: photons, magnons and deuterons; but possibly including Cooper pairs of protons in certain conditions where they function as a single particle. This is another reason why Holmlid’s theory is alluring. All three BEC candidate particles do show up in his experiments. As QM parameters, there should be probability enhancement between them. Curiously – if you look at google images for BEC-photon – the most common light frequency to be successfully trapped is in the mid 500 nm range which is green to yellow-green. Is it coincidental that Holmlid uses laser light in this frequency range? Possibly not, since it is a common laser frequency, but if there is a connection it could also relate to the magnon as a BEC. See: Demokritov, S.O. et al “Bose-Einstein condensation of quasi-equilibrium magnons at room temperature under pumping”, Nature, vol. 443, September 2006. So here we have a condensation mechanism whereby coherent photons can combine with coherent magnetic waves, and then combine with deuterons and the result could be densification at ambient temperature and pressure (so long as the BEC state is maintained).
