用laser干涉仪探测超轻轴子暗物质风

Detecting ultralight axion dark matter wind with laser interferometers

Arata Aoki, Jiro Soda

摘要:

质量在$10^{-22}$ eV左右的超轻轴子被认为是暗物质的候选者。超轻轴子的一个特殊特征是随时间振荡的压力,这会产生引力势的振荡。由于太阳系以大约$v \sim 300 \, \text{km} / \text{s} = 10^{-3}$的速度穿过暗物质晕,因此存在轴子风,对我们来说,它看起来像标量引力波。因此,有可能通过使用激光干涉仪探测器来探测具有宽质量范围的超轻轴子暗物质。我们计算了由超轻轴子场的振荡压力引起的探测器信号,这将被未来的激光干涉仪实验所探测到。我们还认为,探测器的信号可以增强由于共振的修正引力理论解释的暗能量。

英文摘要:

The ultralight axion with mass around $10^{-22}$ eV is known as a candidate of dark matter. A peculiar feature of the ultralight axion is oscillating pressure in time, which produces oscillation of gravitational potentials. Since the solar system moves through the dark matter halo at the velocity of about $v \sim 300 \, \text{km} / \text{s} = 10^{-3}$, there exists axion wind, which looks like scalar gravitational waves for us. Hence, there is a chance to detect ultralight axion dark matter with a wide mass range by using laser interferometer detectors. We calculate the detector signal induced by the oscillating pressure of the ultralight axion field, which would be detected by future laser interferometer experiments. We also argue that the detector signal can be enhanced due to the resonance in modified gravity theory explaining the dark energy.
