For those interested (and with subscriptions or institutional access), here are the abstracts for the two papers, the first from the MIT group and the second from the Princeton group:<p><a href="http://www.sciencemag.org/content/early/2015/07/15/science.aaa9273.abstract?sid=31d8c875-11ca-4da8-aeeb-32719f4e4395" rel="nofollow">http://www.sciencemag.org/content/early/2015/07/15/science.a...</a><p><a href="http://www.sciencemag.org/content/early/2015/07/15/science.aaa9297.abstract?sid=31d8c875-11ca-4da8-aeeb-32719f4e4395" rel="nofollow">http://www.sciencemag.org/content/early/2015/07/15/science.a...</a><p>The MIT group's paper appears to be on arXiv: <a href="http://arxiv.org/abs/1502.03438" rel="nofollow">http://arxiv.org/abs/1502.03438</a> (albeit with a somewhat different abstract; perhaps a pre-acceptance version). Unfortunately the Princeton group's paper doesn't appear to be posted on arXiv.org as of right now.
I'm confused. It sounds like they though neutrinos were Weyl points, and neutrinos are real particles. But it also sounds like this experiment created quasiparticles. So are Weyl points still a proposed real particle? Or was it only ever theorized to be some kind of emergent phenomenon? Or did they really create a new type of real particle?
>That issue of scalability in optical systems is “quite fundamental,” Lu says; this new approach offers a way to circumvent it. “We have other applications in mind,” he says, to take advantage of the device’s “optical selectivity in a 3-D bulk object.” For example, a block of material could allow only one precise angle and color of light to pass through, while all others would be blocked.<p>Putting my science fiction hat on, if that meant you could build a light-absorbing material you could potentially have (for instance) camouflage that reflected on a certain wavelength only known to your friendly forces. Or hidden assets that require a filter to see - hidden keypads, hidden instructions, that kind of thing.
No way! I read about chaos theory butterflies. But now you're saying butterfly wings contain <i>whales</i>? Gnarly, man.<p>On a more serious note, it's good to see Zhejiang University from China in there. Their library also provides the only scanned copies online of some important ancient Chinese historical sources. Except for the big name unversities in China (Tsinghua, Fudan, etc.), this is a university to watch.
For a moment, I confused Weyl points with Ley lines and was shocked by disbelief.<p>Ley lines: <a href="https://en.wikipedia.org/wiki/Ley_line" rel="nofollow">https://en.wikipedia.org/wiki/Ley_line</a>
