In condensed matter physics, Dirac cones can be found in graphene, topological insulators, cuprates, and iron-pnictides. This means that electrons behave as massless particles near the Dirac points.

What is the significance of this in condensed matter physics? Why is this surprising? Are there any potential applications?
