论文摘要
为了检测高频引力波，我们需要一种新的检测方法。在本文中，我们使用腔中使用镁来为重力波检测器开发形式主义。使用费米正常坐标并采用非相关性极限，我们在引力波背景中获得了镁的哈密顿量。考虑到哈密顿量，我们展示了如何使用镁来检测高频引力波。此外，作为镁重力波检测器的演示，我们通过利用木元实验的已知结果进行轴突暗物质搜索，从而给GHz重力波提供了上限。
In order to detect high frequency gravitational waves, we need a new detection method. In this paper, we develop a formalism for a gravitational wave detector using magnons in a cavity. Using Fermi normal coordinates and taking the non-relativistic limit, we obtain a Hamiltonian for magnons in gravitational wave backgrounds. Given the Hamiltonian, we show how to use the magnons for detecting high frequency gravitational waves. Furthermore, as a demonstration of the magnon gravitational wave detector, we give upper limits on GHz gravitational waves by utilizing known results of magnon experiments for an axion dark matter search.
