轴子暗物质模型中的量子破裂

Quantum break 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)的轻轴子系统具有不稳定性,如果由量子破裂引发(这消除了对种子的需要),它可以以相干方式快速混合成光子对。增加更多的光子态,例如静止的轴子场的多重角度,会使混合时间中对数因子的自变量减少几个数量级。在不稳定的窗口内允许多个光子态,会导致一种同步效应,似乎使传统的红移限制无效。即使电磁场的充分发展状态也是高度非经典的;它们可以被看作是不同的近经典宏观系统的量子叠加。

英文摘要:

A system of light axions comprising a classical axion field, one candidate for dark matter, has an instability that can rapidly mix in photon pairs in a coherent fashion if initiated by a quantum break (which eliminates the need for seeds.) Adding more photon states, such as a multiplicity of angles for the case of the axion field at rest, reduces the argument of a logarithmic factor in the mixing time by orders of magnitude. Admitting multiple photon states, all within a window of instability, leads to a synchronization effect that appears to nullify conventional red-shift limitations. Even the fully developed states of the electromagnetic field produced are highly non-classical; they can be looked on as quantum superpositions of different nearly-classical macroscopic systems.
