电偶极矩、类轴子粒子和致密暗物质毛探测器的偶极放大器
A dipole amplifier for electric dipole moments, axion-like particles and a dense dark matter hairs detector
摘要：
一种工具，可以限制，在几分钟内，超出标准模型参数，如电偶极矩（EDM）下降到一个下限$d_\text{e}^{\cal{N}}<10^{-37}\text{e}\cdot\text{cm}$在散装材料，或耦合的类轴子粒子（ALP）光子下降到$|G_{aγγ}|<10^{-16}$ ~GeV $^{-1}$，描述。对于中子EDM，最佳极限为$d^n_e<3\cdot10^{-26}\text{e}\cdot\text{cm}$，而对于$|G_{aγγ}|<6.6\cdot10^{-11}$，最佳极限为~GeV $^{-1}$。{ \it偶极放大器}由沉浸在环形磁场中的超导回路构建而成，即$\vec{B}$。当在伦敦穿透深度的核磁矩与$\vec{B}$对齐时，体磁化总是伴随着EDM诱导的体电场$\vec{E}\propto\vec{B}$，其产生具有特征频率$ω_{\text{D}}\propto d_\text{e}^{\cal{N}}$的可检测的振荡超电流。冷暗物质（CDM）ALP在形式上是相似的，其中$ω_\text{D}\propto |G_{aγγ}|\sqrt{n_a/(2m_a)}$和$m_a$是ALP质量，$n_a$是数密度。如果$|G_{aγγ}|\sqrt{n_h/(2m_a)}>4.9\cdot10^{-27}$其中$n_h$是毛发中的ALP数密度，则具有偶极放大器的穿过暗物质毛发的空间探测器足够灵敏以检测ALP密度变化。
英文摘要：
A tool that can constrain, in minutes, beyond-the-standard-model parameters like electric dipole moments (EDM) down to a lower-bound $d_\text{e}^{\cal{N}}<10^{-37}\text{e}\cdot\text{cm}$ in bulk materials, or the coupling of axion-like particles (ALP) to photons down to $|G_{aγγ}|<10^{-16}$~GeV$^{-1}$, is described. Best limits are $d^n_e<3\cdot10^{-26}\text{e}\cdot\text{cm}$ for neutron EDM and $|G_{aγγ}|<6.6\cdot10^{-11}$~GeV$^{-1}$. The {\it dipole amplifier} is built from a superconducting loop immersed in a toroidal magnetic field, $\vec{B}$. When nuclear magnetic moments in the London penetration depth align with $\vec{B}$, the bulk magnetization is always accompanied by an EDM-induced bulk electric field $\vec{E}\propto\vec{B}$ that generates detectable oscillatory supercurrents with a characteristic frequency $ω_{\text{D}}\propto d_\text{e}^{\cal{N}}$. Cold dark matter (CDM) ALP are formally similar where $ω_\text{D}\propto |G_{aγγ}|\sqrt{n_a/(2m_a)}$ with $m_a$ the ALP mass and $n_a$ its number density. A space probe traversing a dark matter hair with a dipole amplifier is sensitive enough to detect ALP density variations if $|G_{aγγ}|\sqrt{n_h/(2m_a)}>4.9\cdot10^{-27}$ where $n_h$ is the ALP number density in the hair.
