| - | In addition, the electrodynamics and especially the Maxwell equations are modified if [[models:speculative_models:axion|axions]] exist. This is known as [[https://inspirehep.net/record/1337434/files/26-Kuriksha.pdf|axion electrodynamics]] and was first noted in F. Wilczek, Phys. Rev.

The main idea here is that if the theta parameter can change in space and time $\theta=\theta(x,t)$, the term $\theta F \tilde F$ directly influences the equations of motion. This is discussed explicitly in Section 1.2 "The Theta Term" in [[http://www.damtp.cam.ac.uk/user/tong/gaugetheory/gt.pdf|Tong's lectures on gauge theory]]. |
