轴子暗物质模型中的轴子、光子对混合

Axion, photon-pair mixing in models of axion dark matter

R. F. Sawyer

摘要:

一个包含经典轴子场(暗物质的候选者之一)的轻轴子系统具有一种不稳定性,如果系统最初被某种微量的光子对混合所播种,这种不稳定性将以相干的方式迅速混合。我们开发了包含混合的方程,同时结合了足够的量子力学来消除对种子的需要。扩展到许多模式带来了许多有趣的问题。例如,在混合时间中不可避免的对数因子的论点减少了许多数量级;关于红移的担忧被搁置,就像那些与原始轴子状态的块状有关的担忧一样。我们进一步看到,在我们的解中,即使电磁场的充分发展状态也是完全非经典的。

英文摘要:

A system of light axions comprising a classical axion field, one candidate for dark matter, has an instability that would rapidly mix in photon pairs in a coherent fashion if the system were initially seeded by some tiny amount of such mixing. We develop equations that contain the mixing and at the same time incorporate enough quantum mechanics to eliminate the need for seeds. Extending to many modes brings many interesting issues to the fore. For example, the argument of the inevitable logarithmic factor in the mixing time becomes reduced by many orders of magnitude; concerns concerning red-shifts are laid to rest, as are those related to lumpiness of the original axion state. We further see that even the fully developed states of the electromagnetic field are completely non-classical in our solutions.
