Examples

Once researchers knew that electrons could pair in a superconductor, they began thinking about how fermions might pair in other condensed matter systems.

Now, there's great interest in forming molecules from fermions.

You could also do something with fermions here.
Then we look at the fermions and we see what G is.
These are called the fermions, and these are the bosons.
But atoms with half-integer spins—fermions—are excluded from occupying the same quantum states.

Academic text (2003)
A prominent example is supersymmetry, in which each standard-model boson is partnered with a new fermion—and vice versa.

Academic text (2012)
Thus, the low-density gas might give interesting insight into other strongly interacting systems of fermions, such as the electrons in high-Tc superconductors or the quarks in a quark-gluon plasma.

Academic text (2005)
Electrons, neutrinos, and a host of other subatomic particles belong to a family called fermions.
On the other side stand the fermions, the particles that react to those forces: electrons, quarks, and the like.

Morphology

fermion = Fermi (semi-transparent) = Fermi + on

The suffix '-on' marks particle names (so learners familiar with words like 'electron' or 'proton' can guess it's a particle), but the specific statistical property (obeying Fermi-Dirac statistics) is specialized and not inferable from the base.

Etymology

The word fermion is 'named after' the Italian scientist Fermi plus the common particle ending -on, the same ending seen in electron and proton. So a fermion is a tiny particle like an electron, proton, or neutron, and the name helps you remember it is in the group of particles that cannot occupy the same quantum state.
