论文摘要
该白皮书在轴心理论的几个不同方面收集了一些开放问题。这些问题与轴突耦合，轴磁单极系统，量子重力理论中的轴，轴支弦/域壁系统中的轴以及轴心耦合的热摩擦有关。他们展示了许多轴心理论的机会，这些理论需要更多的研究。
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.
