论文摘要
witten效应意味着轴和磁性单极之间的电磁相互作用。基于量子电磁动力学，通过引入两个四个四电位（$ a^μ$和$ b^μ$）来描述光子，建立了通用的低能轴 - 光子有效场理论。与普通的轴耦合$ G_ {Aγγ} af^af^af^af^{uldect af^af^{uldect af^{uldem g_ {aab} af^af^{μg_{aab {aab} $ {结果，传统的轴麦克斯韦方程将进一步修改。我们正确求解了新的轴突修饰的麦克斯韦方程，并在给定静态电场或磁场的情况下获得了轴突诱导的电磁场。事实证明，在外部磁场和电场的存在下，可以探测主要的耦合$ g_ {aab} $和$ g_ {abb} $。与具有较大康普顿波长的轴的电场相比，诱导的振荡磁场总是被抑制。这与搜索亚$ $ $ eV轴诱导的振荡磁场的常规实验中的情况相反。因此，我们提出了新的策略，以测量Haloscope实验中亚$ $ EV轴的新耦合。
The Witten effect implies the electromagnetic interactions between axions and magnetic monopoles. Based on the quantum electromagnetodynamics, a generic low-energy axion-photon effective field theory was built by introducing two four-potentials ($A^μ$ and $B^μ$) to describe a photon. More anomalous axion-photon interactions and couplings ($g_{aAA}$, $g_{aBB}$ and $g_{aAB}$) arise in contrary to the ordinary axion coupling $g_{aγγ}aF^{μν}\tilde{F}_{μν}$. As a consequence, the conventional axion Maxwell equations are further modified. We properly solve the new axion-modified Maxwell equations and obtain the axion-induced electromagnetic fields given a static electric or magnetic field. It turns out that the dominant couplings $g_{aAB}$ and $g_{aBB}$ can be probed in the presence of external magnetic field and electric field, respectively. The induced oscillating magnetic fields are always suppressed compared with the electric fields for the axions with large Compton wavelengths. This is contrary to the situation in conventional experiments searching for the oscillating magnetic fields induced by sub-$μ$eV axions. Thus, we propose new strategies to measure the new couplings for sub-$μ$eV axion in haloscope experiments.
