AI中文摘要：
我们提出一种基于外部磁场中长盘绕光纤的类轴子粒子（ALP）探测新方法。通过纳入横向边界条件与光纤弯曲效应，构建了描述该几何结构中光子-ALP转换所需的理论框架。对于折射率远大于1的固体二氧化硅光纤，我们表明主导信号为光子的相移，而ALP产生导致的损耗可忽略不计。该装置有潜力在大ALP质量区域设定新的约束条件。我们进一步确定了边界效应变得重要的参数区域，特别是对于空芯光纤，ALP产生的信号可显著增强。
英文摘要：
We propose a new approach to axion-like particle (ALP) searches based on long, coiled optical fibers in an external magnetic field. We develop the theoretical framework required to describe photon-ALP conversion in this geometry by incorporating transverse boundary conditions and fiber bending. For solid silica fibers with refractive index considerably larger than unity, we show that the leading signal is a phase shift of the photon, with negligible loss due to ALP production. This setup has the potential to set new constraints in the regime of large ALP mass. We further identify parameter regions in which boundary effects become important, in particular for hollow-core fibers, where signals due to ALPs can be significantly enhanced.
