Now w're getting somewhere:"Photons are harder to categorize, it all depends, but i'd say laser light behaves more like waves than particles"
Mc Carthy says in his "Ultimate alchemy" that electrons behave like waves because of confinement. Ok for that. If the photons these electrons are emitting upon falling back to the conduction band did no longer behave as particles, this would have been a really extraordinay finding and hence certainly be mentioned in Mc Carty's article.
Photons are not hard at all to categorize, quantum mechanics is quite clear about the issue, wave-particle dualism. What seems to be the case, accordng to my physicist/quantum laser collegue, is that the probabilities for one or the other behaviour are different. Which still means that laser light always has both wave and particle character. Pulsed lasers for instance behave more as particles.
You should not think yourself about how q-dot photons behave. The fact that you have to think about it further clearly indicates that there is no scientific publication concerning the non-particle behaviour of q-dot photons. Otherwise you would be able to cite it right away.
As for turntables, I'm sure that you can measure the effects of the waves hitting on the shoreline (the beach here is only some 3 km away). However, I believe that platter bearing rumble has more influence on sound than seismic waves well below the table suspension resonance frequency. I further believe that what has been called by J. Moir "acoustic breakthrough" is of more importance than seismic phenomena.

Follow Ups:
So I am now accused of thinking about it? -- hahah funny!There are QDs and then there are QDs. Most QDs radiate monochromatic (but non-coherent light); however there is a new class of QDs in town the last few years - QD lasers that emit coherent photons when illuminated by another laser source. These special QDs are noted by "cladding" used to intensify confinement plus use of QD arrays to take advantage of "interaction" among dots and promote coherent light emission.
I hope we agree that coherent light is quite different from ordinary light (non-coherent) light. I.e., so all light is not the same :-)
An interesting thing (pretty sure you will agree) is that Al, Gallium, Ni cladding and copper dopants are used specifically in some of these special QD lasers.
Sesimic isolation is something that must be demonstrated to be believed - like a lot of thing audio-related :-). Even 8 years after the so-called isolation revolution, many people dismiss seismic influence out of hand. I have been building seismic isolation devices for 8 yrs, including a 6 DOF sub-1 Hz platform.
Not all light is the same, no problem with that. But photons are photons, all the same, all acting as wave and particle. It's not because there is some advanced Q-dot devices that all of a sudden photons change the inherent bevahiour. If yes, then there is some publication is a serious scientific journal.It might well be that this new type of Q-laser exist, shall I ask our expert or are you willing to post a link? If it's cascaded q-laser, that's an old hat. But in order to activate such q-laser by using laser you have to put the q-laser right into the source laser beam which you don't do by simply placing your chip somewhere onto you CD player.
All sorts of chemical elements are used for doping but you've said yourself that Allen's EM machine was not able to make an alaysis of the dot itself. So the EM would not detect any dopant present in the q-dot.
What I find quite amusing is that people go to great lenghts to isolate their gear by using pods, platforms, cones, you name it, but put their turntable in a corner or against the wall, or between the speakers. I made some experiments myself to see the effects of acoustic breakthrough (sound from speakers affecting the turntable) and in my former setup I could detect such breakthrough but don't think that it really is a problem. I also tested some cables and the effect of absolute polarity and found that I couldn't hear any difference. So for me I'm fine without all that stuff,I decided to put my money where it is important, i.e. speakers and software.

K - The point about coherent light is it's much more wavelike (than ordinary light) due to being "in phase" and having one direction; therefore when coherent light interacts with matter the effects are much greater than for ordinary light. This is precisely the *entire point* why QDs react to laser light so intensely and why QDs (emission) can have such an effect on matter. This is why there is so much intense interest in QDs (I keep reminding you) - it is like discovering brand new atomic elements!Just Google "Quantum Dot Laser" also "quantum dot array"- it's all over the internet, has been for many years..The fact that QDs lase should not be very surprising as we have known quantum well lase since the 1970s! There is not too much difference between the well and the dot, same basic principle, altho the dot is more powerful in many respects due to better confinement.
There is quite a ways to go, we might not agree on all the pertinent points involved by Christmas :-)

I'm glad to note that you don't maintain the point of q-dots photons not behaving as particles!It's also interesting to note that now it's q-dot laser, not simple q-dots as it has been some weeks ago. What can we expect next: quantum computing? Did JSMR tell you the whole story or are you just speculating?
"why QDs react to laser light so intensely "
basically I agree. But as far as the chip is concerned, you still did not explain why laser light is reflected by the CD's Al-layer but manages to get through the players solid metal housing.
"why QDs (emission) can have such an effect on matter."What effect do q-dots have on matter? What effect does the chip's q-dots have on matter?
By Xmas this year the explanation should be ready, wrapped up nicely, free from bugs and bullet-proof.Klaus
I perform due diligence. All things in due time. I'm fairly confident you're not prepared for the full story :-)
Well, looking at what has been said about that unfortunate chip these last weeks and months I'm prepared for about anything: will the chip cause another Big Bang?What I don't quite understand is that due diligence and due time thing: you don't have to apply serious R%D just to know what's on that chip and how it works? The manufacturer should precisely know all the answers to all the questions, should he not?
But go on, finish your story, it's much easier to rip it apart once we know exactly what to look for. But you will apply the due diligence to back up that story with hard facts, will you? This "butterfly" tactics (q-dots here, q-dot laser there, then let's look at coherent light and wave-particle dualism) is nice when youy're a butterfly and used to it. But I've got more interesting things to do than travel on q-planet, as interesting that might be.
I suggest that we stop here, I'll post a reminder every now and then, and I'll read funny audio reviews in the meantime. Oh yeah, and I have to apply some tweaks to my system:-) Maybe that I should try one of these magic AC-fuses? And I have to decide on a HDD DVD recorder. And connect my active kitchen speaker. And read more funny audio reviews.

Klaus - agree, let's put this baby to bed for a while. I think i might have learned something. Thanks for putting up with my antics.I dont think that amp manufacturers are forced to reveal the theory of electricity or their propritary circuits, but then who's asking?
G
Klaus,The homework Geoff keeps trying get you to do is watch a Charlie Brown special.
Pay special attention to the interactions between Charlie and Lucy.
Cheers,
Pete
