Interesting information Xavier. The high Q nature of the resonances suggests that the circulating plasmon currents may not be subject to significant resistive losses. Is it possible that these currents are flowing within a super conductive structure? I would expect large spheres of these types of material to be subject to standard resistive losses that would broaden any resonance that appears due to size and shape. Are you aware of any transition effects that occur as the size of the particle is reduced? An example would be the appearance of highly sharpened spectral line resonances which shows up as the size of the nanoparticle is significantly reduced. An effect like this would imply that the atoms within the nano sized structure are acting in a manner somewhat as a high temperature condensate.
Can anyone compare the line resonances seen in the nanoparticles to the line resonances associated with atomic responses? I am particularly curious about the bandwidth of the resonances about their center frequencies. Have you seen references to the coefficient of coupling that exists between nanoparticles resonances? I suspect that each individual particle resonant frequency lines would be extremely dependant upon the exact size if of high Q. This would tend to make coupling far less efficient due to tuning differences. I located some interesting information concerning pregnancy testing per your suggestion Xavier. I would have never guessed that this detection technology existed!

Thanks for posting it. I wonder if anyone has seen papers that show the resonances and quality factor associated with the size of the material. Can a small activation at the correct wavelength of electromagnetic radiation lead to a large plasmon current flow? Yes. For a really good example of this, read up on pregnancy etectors. Basically you have gold nanoparticles whose plasmon esonance can be seen optically (they look red) when a certain hormone inds to their surface. > Also, it would be interesting to see if the individual nano scale plasmon resonances would magnetically couple and thus share energy. I've seen this with nanorod arrays, where plasmon resonance couple to ach other, but I'm pretty sure it's not magnetic coupling (plasmons re TM waves). > In the same line of thought, would this form of coupling tend to smooth out what would otherwise be very precise energy levels? I think you still get very sharp linewidths, even with coupling. > Dave -----Original Message----- From: Peter Gluck <[email protected]> To: VORTEX <[email protected]> Sent: Thu, Mar 22, 2012 6:34 am Subject: [Vo]:nanoparticles in LENR Quantum Plasmons Demonstrated in Atomic-Scale Nanoparticles http://www.sciencedaily.com/releases/2012/03/120321143017.htm This can be important for LENR Peter PS I cannot solve my "Chrome kills hyperlinks" problem- very bad for my blog, I can only by-pass it by using Internet Explorer Do you have some experience with it? -- Dr. Peter Gluck Cluj, Romania http://egooutpeters.blogspot.com
