MIT Physicists Build World's First Fermion Microscope

Posted by samzenpus on from the all-the-better-to-see-you-with dept.

Zothecula writes: Researchers working at the Massachusetts Institute of Technology (MIT) claim to have created a method to better observe fermions – the sub-atomic building blocks of matter – by constructing a microscope capable of viewing them in groups of a thousand at a time. A laser technique is used to herd the fermions into a viewing area and then freeze them in place so all of the captured particles can be imaged simultaneously.

    But actually the third group. The groups of Stefan Kuhr of the University of Strathclyde and Marcus Greiner in Harvard were first.

    A laser technique is used to herd the fermions

    So ... do fermions most resemble cows, or cats? I'm confused.

      Well, fermions are called that because they exhibit Fermi-Dirac statistics, so they're arguably more like cats than cows.

      Fermions => cats

      Bosons => cows

      (Bosons can be herded into the same quantum state, fermions cannot on account of the Pauli exclusion principle.)

      A new standard has been set. Now I will demand a cat/cow analogy every time. Seriously this makes it clear why this is neat, at least to me it did.

    That's because they've been listening to Barry-White-ions.

    Most scientists don't know about them because you have to search in lower frequency ranges.
