When cooled to very low temperatures, two or more electrons behave as if they were a single particle.

This can give the material some exotic properties.

In some materials, electrons form into couples known as Cooper pairs that move through the material without facing any electrical resistance.

This symmetry in turn gives rise to special quantum states on the surface of the material known as Majorana fermions.
