Description
Axions and axion-like particles are well-motivated dark matter candidates whose relic abundance is often attributed to the standard misalignment mechanism. After briefly reviewing the conventional picture, I will discuss several non-minimal realizations of axion dark matter, including trapped misalignment, bubble misalignment, and level crossing in multi-axion systems, which can qualitatively alter the production and distribution of dark matter.
