论文摘要
我们提出了一种新型技术，以搜索充满了诸如超富氦之类的材料的光力学腔。轴突吸收将泵激光光子转换为光子和声子。腔中相干光子或声子的高职业数量提高了轴突的吸收率，从而使我们的建议在很大程度上可以克服极其小的轴突耦合。探测的轴质量是由在最终状态和Stokes模式下产生的光子的相对频率设置的。因为轴突质量和动量都不需要与腔体的物理大小相匹配，所以我们可以扩大腔体的大小，同时保持对其他腔量的辅助量的范围辅助量。
We propose a novel technique to search for axions with an optomechanical cavity filled with a material such as superfluid helium. Axion absorption converts a pump laser photon to a photon plus a phonon. The axion absorption rate is enhanced by the high occupation number of coherent photons or phonons in the cavity, allowing our proposal to largely overcome the extremely small axion coupling. The axion mass probed is set by the relative frequency of the photon produced in the final state and the Stokes mode. Because neither the axion mass nor momentum need to be matched to the physical size of the cavity, we can scale up the cavity size while maintaining access to a wide range of axion masses (up to a meV) complementary to other cavity proposals.
