Some open questions in axion theory
Abstract
This white paper collects some open questions in several different aspects of axion theories. The questions are related to quantization of axion couplings, axion-magnetic monopole systems, axions in quantum gravity theory, axion string/domain wall systems, and thermal friction from axion couplings. They demonstrate many opportunities for axion theory, which call for more studies.
