Low-energy nuclear reaction (LENR) in condensed matter is a very challenging topic due to the complex control parameters to reproduce the experiments, and the remarkable impact to human society. The resonant tunnelling optical model with coupled complex potentials [1] is very interesting due to its simplicity and interoperability.
The model includes a complex Coulomb barrier with a positive real part and negative imaginary part, coupled with a complex nuclear well with a negative real part and positive imaginary part. Physically, the positivity in imaginary part denotes the absorption nature, and the negativity in imaginary part denotes the emission nature.
However, it is very hard to understand for emission nature of Coulomb barrier.
Here, we proposed a hypothesis of coherent emission of the excited surface and/or sub-surface atoms contributed to the negative imaginary part of Coulomb barrier, and then to the origin of LENR. Typically, excited surface phonons are incoherent due to the random inter-atomic collisions.
The possible factor is to locally excite the surface phonons and result in the Bose-Einstein condensation.
In particular, the localized anharmonic vibrations proposed by Dubinko et al might be one of the possible ways to realize the localized excited coherent surface phonon [2]. We calculate the phonon band structure of PdH and PdD by considering the anharmonic vibrations, and try to bridge the gap of the localized anharmonic vibrations and the emission nature of surface phonons.
The proposed mechanism might be useful for understanding some LENRs triggered by thermal heating, THz pumping, gas pumping or inflating, etc.

What I consider very intriguing is this sentence: The possible factor is to locally excite the surface phonons and result in the Bose-Einstein condensation.

If someone says stop, then stop. Do not enter onto a thread on a topic you don’t like just to disrupt, rattle cages, poke sticks, insult the regulars, or engage in trolling activities, etc. ~Jim Robinson
The issue isn’t whether we allow skepticism, it is whether we allow hyperskeptics and skeptopaths to ruin the scientific dialog. Such FReepers who persist in polluting these threads have been asked to leave, and we are asking that they open their own threads if they have comments.

I’m gonna say, “Yes?”
Please remove me from the ping list.
All the same crap that you include at the beginning of every post is irritating as hell.
Okay, removed.
