[Vo]:Resonances: Coupling between electronic states and vibrational modes (phonons)...
Mark Iverson-ZeroPoint Wed, 25 Jan 2012 13:28:21 -0800
FYI:
The presence of excess heat, and [near] lack of high-E particles/photons
from LENR reactions would require coupling the large amount of E into the
lattice vibrations (phonon modes) instead of into gammas (photons) or
particles (neutrons and subsequently, dead grad-students). The article
below looked into the energy-transfer (coupling) process in photosynthesis.
They discovered that the coupling between electronic states and vibrational
modes is greatly enhanced when they hit the light-harvesting complexes of
algae with a 2-color (wavelength) photon spectroscopy.
How does this apply to LENR? According to DGT, the form of LENR used in
their technology (and likely all Ni-H gas-phase experiments) is a
'multi-stage' process. One of those stages is the coupling of the excess
[nuclear] energy into the lattice instead of the usual gammas or energetic
particles. I would posit that there is something unique about the geometry
of the H-loaded metal lattice and the AMOUNT of heat energy that is present
which determines the frequency of the lattice vibrations (phonons), which
establishes a coherence similar to the below article which couples energy
from electronic states to vibrational modes. The difference is that LENR
would be coupling nuclear energies to the lattice... or could there be
coupling from nuclear to electronic, and then from electronic to phononic?

Key phrases:
"By using the newer, less common technique, called two-color photon echo
spectroscopy, the researchers could excite only the pathway in which
[quantum] coherence occurs. Singling out this pathway revealed clear
signatures for strong coupling between the electronic states and the
vibrational modes of the protein matrix (phonons)"
"Our observation of strong coupling between the electronic states and the
phonon modes of the protein matrix provides strong experimental evidence
that classical treatment of these interactions is not sufficient,"
>From the paper's abstract:
"... allowing coherent coupling between otherwise nonresonant
transitions."

Longer excerpt from PhysOrg article:
------------------------------------
"... the quantum coherence in the algae's light-harvesting complexes was
originally observed using 2D electronic spectroscopy, which uses short,
broadband pulses to probe energy dynamics. The use of broadband pulses
(i.e., pulses with a wide range of frequencies) excites many different
pathways simultaneously. Although this technique can be useful, it also
makes it difficult to isolate different processes since multiple excitations
can interact and alter each other's dynamics.
By using the newer, less common technique, called two-color photon echo
spectroscopy, the researchers could excite only the pathway in which
[quantum] coherence occurs. Singling out this pathway revealed clear
signatures for strong coupling between the electronic states and the
vibrational modes of the protein matrix (phonons) in the algae's
light-harvesting complexes. As Davis explained, this type of interaction is
not what is expected from the classical models that have traditionally been
used to describe light harvesting and energy transfer in photosynthesis.
"Our observation of strong coupling between the electronic states and the
phonon modes of the protein matrix provides strong experimental evidence
that classical treatment of these interactions is not sufficient, and that
models including the microscopic details of the coupling interactions are
indeed required," Davis said. "The quantum nature of these interactions
increases the scope for quantum effects to have an impact and enhances the
possibility of coherent energy transfer in photosynthesis."
In the future, the researchers plan to further extend the technique to
investigate these quantum mechanical interactions and the role they play in
light harvesting and energy transfer.
"We are currently exploring the dependence of these coherent interactions on
a number of experimental parameters, including temperature, wavelength and
polarization," Davis said. "These results will enable us to explore the
nature of the excited states, their interactions with the phonon modes of
the protein matrix and the role they play in energy transfer. We also plan
to investigate whether such long-lived coherences also exist between other
states in these systems and ultimately whether coherence transfer between
states occurs and is relevant for photosynthesis."

Sounds a lot like my favorite LENR theorist, KP Sinha.

Methinks nuclear modes are in different energy regimes than phonons or electronic excitations: and one would need a mechanism to transfer energy between nuclear excitations and the electron "sea"...haven't done any solid state theory so all I can do is point at the type of thing to look at.
Cheers!
How about a ‘simple’ layman’s explanation of the implications??
I think he’s just showing off! (But I’ll hang around to see if there is a reply I can understand!)
LOL.
I think Kevmo is a fun dude with a great mind.
However . . . as my teen pastor used to say . . .
Gotta get the hay down outta the loft where the cows can eat it.
I’m fascinated by LENR, but don’t have enough physics background to understand it very well. Can anyone recommend a book or article explaining what’s involved which can be understood by someone with only a high school physics background?
This one is on-line, free, and has a pretty good introduction. It later gets into more depth:

Other books, videos, etc.:
http://www.lenr-canr.org/Introduction.html
I agree with WW. In particular, the book “Excess Heat” is a good read.
OK, here’s my swag.
Basically Phonons are Bosons (electron pairs that are somehow ‘special’). And it is Bosons that are the basis of KP Sinha’s theories.
Here’s how I look at it. Up until now, there’s been no evidence that Phonons/Bosons/Lochons convert their energy from vibration to ‘the grid’, which would mean heat or maybe even electricity.
But here we have an example of it happening in Nature.
And KP Sinha’s theory promotes that possibility (even before this result was developed) as the explanation not only for LENR but for superconductivity as well.
Here’s another way I look at it. Phonons are like blackbirds. Real Small. The ‘grid’, the Palladium (or Nickel) Matrix is like an elephant. Now if I were to tell you that a blackbird could knock over an elephant due ENTIRELY to its kinetic (MOTION) energy, you’d say I was crazy. But blackbirds have been known to swarm in the millions. And they turn on a dime, flying almost as an organic unit. If such an organic unit hit an elephant, it could knock over an elephant. The fascinating thing is... every time we see the elephant get knocked over we see a swarm of blackbirds. And that is the same correlation of excess heat to LENR.
I haven’t seen you be all that active lately, Quix. I thought I saw JimRob tell you to basically stay away from UFO threads or sumthin like that.
Is that the case?
You won't get it. Overall, Kevmo has little concern for the user friendliness of his posts. In addition, part of his strategy is to baffle people into thinking that LENR is a useful science.
Check the recommendations on Amazon, and stay away from the cranks associated with LENR.
Hmmmmmmmm
Sigh.
Thx.

***Moonboy goes out of his way to get things wrong. How would he know my strategy? Has he developed the ability to mindread? At least he’s open about being anti-LENR.
OK.
What do I know.
I’m just a peanut gallery observer.
