Bose-Einstein condensation of photons in a 'white-wall' photon box.
Anyone that know the possible energies of this 'Super photon". It's very interesting as you can do it at room temperatures. Where are the limitations of its 'size' etc? It opens for strange possibilities, doesn't it.
==
No 'size', I know
But super positioning them in one 'point' is here, so?
Like, can you build up its energy to become a particle of 'rest mass'?

What happens when the 'BEC' condensates. Will it accept more photons? And why does it emit light? Shouldn't it just 'intensify' without 'emitting'? The only way you can define something as a photon is in its annihilation normally, as by a detector? It doesn't make sense.
==
"Moreover, a spatial concentration of light into the centre was observed, which is a consequence of the thermalization within the effective photon trapping potential, formed by curved mirrors. This behaviour is evident from the analogy with a trapped gas of material particles of finite temperature, and we expect that the effect can have prospects in the concentration of diffuse solar light."
Do you make sense of that?
I don't. They're still bosons, aren't they?
Since when did bosons begin to act as 'light houses'?
=
Let's break it down. They create a mirrored cavity. It's not important that the photons annihilate and gets recreated for this by the mirror walls. Then they use a fluid dye to set a 'frequency'? Or what do they mean they 'set' by it, the photons 'resonance' becomes the pigments? First I though it was room temperature but reading 'cold cavity' I'm not sure anymore. What is the 'resonance' of a single photon?
==
Maybe you could call a photon/wave duality its symmetry? Instead of 'equivalence'?
Not that it makes it easier to see, but somehow this feels more as waves than 'photons' to me. I don't know, the way they mix waves (frequency) and the idea of a 'defined photon' reminds me of mental juggling.

One thing is sure though, somehow this store the lights energy and if considering coherent waves, as in a laser, also seem to place it in a 'point source' in that 'matter' the dye still must be. It's a incredibly smart idea, and I'm very impressed with it. But I can't say I understand it? Another of those things I wish I did
