  • The usual misleading sensationalistic title. It isn’t the “shape of the electron” at all. A less misleading – but still not quite correct – explanation is that they have determined the statistical distribution of electron quantum states in a material. Very roughly speaking, it tells us where we’re more or less likely to find an electron in the material, and in what kind of state. Somewhat very distantly like a population density graph on a geographical map. Determining such a population density doesn’t mean “revealing the shape of a person”.

    The paper can also be found on arXiv. What they determine is the so-called quantum geometric tensor. I find the paper’s abstract also misleading:

    The Quantum Geometric Tensor (QGT) is a central physical object…

    but it’s a statistical object more than a “physical” one.

    It’s a very neat and important study, and I don’t understand the need to be so misleading about it :(

    I’ve tried different clients: Element web, desktop, and android, and FluffyChat desktop and android. The problems seems to come, as other have written, when the matrix.org server is involved: it’s people from their handle there which experience glitches joining rooms in other servers. It seems this “part” of the fediverse still needs a lot of development.
