MIT physicists snap the first images of "free-range" atoms

&gt; <i>The researchers directly observed atoms known as “bosons,” which bunched up in a quantum phenomenon to form a wave. They also captured atoms known as “fermions”...</i><p>Is this a typo? Aren&#x27;t those subatomic particles? This is repeated throughout the article.<p>...the linked paper[1] is titled: Measuring Pair Correlations in Bose and Fermi Gases via Atom-Resolved Microscopy<p>Maybe i am missing something? i can only read the abstract.<p>[1] <a href="https:&#x2F;&#x2F;journals.aps.org&#x2F;prl&#x2F;abstract&#x2F;10.1103&#x2F;PhysRevLett.134.183402" rel="nofollow">https:&#x2F;&#x2F;journals.aps.org&#x2F;prl&#x2F;abstract&#x2F;10.1103&#x2F;PhysRevLett.13...</a>
