Mordred Posted March 3, 2015 Posted March 3, 2015 Using a new technique scientists managed to photograph wave particle duality. http://actu.epfl.ch/news/the-first-ever-photograph-of-light-as-both-a-parti/ If anyone comes across the arxiv article for this I would enjoy studying it.
hoola Posted March 4, 2015 Posted March 4, 2015 (edited) interesting, if the rest of the spectrum were to be portrayed, would the arc shown be part of a ribbon like wheel, or would there be a gap and/or unsymmetrical? Is that a reflection below it, or part of them? Edited March 4, 2015 by hoola

Strange Posted March 4, 2015 Posted March 4, 2015 (edited) interesting, if the rest of the spectrum were to be portrayed, would the arc shown be part of a ribbon like wheel, or would there be a gap and/or unsymmetrical? Is that a reflection below it, or part of them? It is important to realise that the image in the article is just a visual representation of the data - it is not a literal picture of what was seen. I assume the "spectrum" is just artificial colouring to make the diagram more interesting (it may represent something but it isn't clear what from the article - from the link to the paper, it may be the amplitude of the waveform at that point). And the image below seems to be just a different representation of the same data. EDIT: skimming through the paper, I think the red-to-blue direction is moving away from the nanowire where the standing wave of light is. The colours appear to represent the numbers of electrons (which have increased in energy) detected at each position. What aspect of the picture represents the quantisation? My (very limited) understanding is that it is just the fact that the image can be generated using electrons, which represents quantization. I may be wrong, so I hope someone more knowledgeable can comment. Edited March 4, 2015 by Strange

swansont Posted March 4, 2015 Posted March 4, 2015 This rightly points out that some of the pop-sci reporting has gone a little too far. https://briankoberlein.com/2015/03/04/two-for-one/ Namely, that the wave-particle duality description is too simplistic. The experiment is neat and hard to do, but there was no violation of any QM rule. 2
Mordred Posted March 5, 2015 Author Posted March 5, 2015 Lol I was just about to post Brian's article ya beat me to it. Thanks for the full paper
