论文摘要
在存在QCD轴线暗物质的情况下,原子获得了时间依赖的电偶极矩。这种效果导致核自旋偏振电介质中的振荡电流,这可以共同激发微波腔的电磁模式。我们表明,使用现有技术这样的“极化卤代”可以探索QCD耦合轴的新参数空间的数量级。如果任何空腔吊带板检测到来自轴 - 光子耦合的信号,则升级的极化卤素具有独特的测试能力,可以测试其是否来自QCD轴。
In the presence of QCD axion dark matter, atoms acquire time-dependent electric dipole moments. This effect gives rise to an oscillating current in a nuclear spin-polarized dielectric, which can resonantly excite an electromagnetic mode of a microwave cavity. We show that with existing technology such a "polarization haloscope" can explore orders of magnitude of new parameter space for QCD-coupled axions. If any cavity haloscope detects a signal from the axion-photon coupling, an upgraded polarization haloscope has the unique ability to test whether it arises from the QCD axion.
