The axion is a dark matter candidate with small mass and weak interactions.  Proposed over thirty years ago,
it is the subject of active search efforts around the globe.  Last summer, the final ingredient for realizing the axion in condensed matter was discovered by Angle-Resolved Photoemission Spectroscopy (ARPES) in the insulating antiferromagnet sodium iridate: the surface Dirac electron excitation.  We review axion electrodynamics and discuss prospects for detecting and studying dark matter in condensed matter.
