Mark and Dave-- I would say the protons first come together as Cooper pairs. This anti-parallel alignment may be assisted with magnetic fields associated with the cavity. The paired protons never stop as has been suggested, since they never act like a billiard ball in a classical sense. They are merely deflected from each other because of their repulsion. The initial conditions establish the wave function that governs the entire batch of mass energy in the cavity, including any Li nuclei or electrons or photons that may be present. This is what I would call a coherent system.
IMO the concept of temperature assumes a RANDOM collision and exchange of energy and momentum in a classical sense. In contrast coherent systems are described by DEFINITE wave functions that may change from time to time with changes in boundary conditions. Thus, an atom being part of a coherent system or a separate coherent system itself, does not have a property, properly termed temperature. Temperature only applies to a COLLECTION of coherent systems and is a continuous parameter, not a parameter made up of quanta. Coherent systems have potential energy in the form of binding energy and kinetic energy as well as linear momentum and spin energy, but no temperature.

I suppose it might be defined in that manner as including both motion and excess stored energy, but most of the time when I consider temperature it is a result of the relative motion of the atoms according to our frame of reference. If the atoms are in the form of hydrogen that has been ionized then the individual protons would come to rest relative to each other periodically. Of course protons are tiny objects relative to the cavities that Mark is considering and plenty of them could be contained within one. They would likely repel each other due to having the same positive charge which would allow the storage of energy among the group. This energy storage would be comparable to energy stored within a spring since it attempts to force the protons apart. The real questions are how close do the protons need to be to each other and for how long of a time frame before a reaction takes place. If you have 4 protons at rest and close together does that encourage a BEC type of reaction? I believe that this is what Mark is thinking, but I may have not understand him well. I still tend to believe that some form of magnetic coupling is the key to LENR, perhaps involving the spins of the particles. So far, I have not seen adequate evidence that BEC reactions have anything to do with LENR. I hope that the mechanism will be understood soon as a consequence of the recent increased replication activity.

Relative motion of an atom to itself is zero, so it is at zero kelvin as far as it knows. When a second atom is added to the void, it becomes more complicated but the relative motion of the two must become zero many times per second as they collide and rebound within your assumed cavity. During these brief intervals we have two atoms that are at zero Kelvin from their reference frame. As you add more and more atoms to the mix the amount of time during which zero relative motion exists between them becomes smaller and less likely, but does occur. As long as you keep the number of atoms relatively small that are required to react in the process of your choice, it will have an opportunity to happen many times per second inside each cavity. Multiply that number by the number of possible active cavities within a large object and you get an enormous number of active sites that have the potential to react. If only 4 atoms are required at zero Kelvin in order to react as you may be considering, it seems obvious that this will occur so often that a large amount of heat will be released by a system of that type. When you realize that it seems to be very difficult to achieve an LENR device that generates lots of heat I suspect that the number of reacting atoms confined within the cavity is quite a bit greater than 4. How many do you believe are required in order to combine and in what form is the ash? On the other hand, if a reaction is virtually guaranteed once a modest number of atoms becomes confined inside the void, then the limiting factor might be that it becomes impossible to confine the required number under most conditions. If this situation is the limiting factor, then a higher temperature could well allow more atoms of the reactants to enter into a void of the necessary type as more space become available when the cavity walls open with additional motion. I am not convinced that this type of reaction is the cause of LENR, but at least it should be given proper consideration.

Thus, ‘coherent’ states in condensed matter above absolute zero is almost never seen. The article’s experiment was done in material at room temp, so the observed behavior is a bit of a surprise. Perhaps what they have not yet thought about is that the ‘microcavities’ have no temperature, as I will explain below. This ties in with a point I tried to explain to Dr. Storms, and although I think he realizes my point had merit, he glossed right over it and went off on a different tangent. This was in a vortex discussion about 9 to 12 months ago. The point is this: The ‘temperature’ inside a ‘void’ in a crystal lattice is most likely that of the vacuum of space; i.e, absolute zero, or very close to it. Because, temperature is nothing more than excess energy imparted to atoms from neighboring atoms; atoms have temperature; space/vacuum does not. Without atoms (physical matter), you have no temperature. In a lattice void, if it is large enough (whatever that dimension is), there is NO ‘temperature’ inside since the void contains no atoms. If an atom diffuses into that void, it enters with whatever energy it had when it entered, so it has a temperature. At this time, I have not heard any discussion as to whether the atoms which make up the walls of the void shed IR photons which could get absorbed by an atom in the void and increase its temperature, however, would that atom want to immediately shed that photon to get back to its lowest energy level??? So voids in crystals likely provide an ideal environment for the formation of BECs. -mark iverson ARTICLE BEING REFERENCED Strong light–matter coupling in two-dimensional atomic crystals http://www.nature.com/nphoton/journal/v9/n1/full/nphoton.2014.304.html Abstract “Two-dimensional atomic crystals of graphene, as well as transition-metal dichalcogenides, have emerged as a class of materials that demonstrate strong interaction with light. This interaction can be further controlled by embedding such materials into optical microcavities. When the interaction rate is engineered to be faster than dissipation from the light and matter entities, one reaches the ‘strong coupling’ regime. This results in the formation of half-light, half-matter bosonic quasiparticles called microcavity polaritons. Here, we report evidence of strong light–matter coupling and the formation of microcavity polaritons in a two-dimensional atomic crystal of molybdenum disulphide (MoS2) embedded inside a dielectric microcavity at room temperature. A Rabi splitting of 46 ± 3 meV is observed in angle-resolved reflectivity and photoluminescence spectra due to coupling between the two-dimensional excitons and the cavity photons. Realizing strong coupling at room temperature in two-dimensional materials that offer a disorder-free potential landscape provides an attractive route for the development of practical polaritonic devices.”
