AI 中文摘要
我们研究光与非相对论性宇宙中微子背景（CNB）的相互作用，提出采用相干激光源和两种不同压缩算符的单臂激光干涉仪来探测该相互作用。我们分析了干涉仪在四种不同量子机制下的感应相移：标准量子极限（SQL）、海森堡极限、具有N^(3/2)增强的超海森堡极限，以及具有N^2增强的超海森堡极限，其中N为干涉仪中的光子数。我们证明，N^2超海森堡增强机制有潜力探测低至10^(-25) μ_B的磁矩，μ_B为玻尔磁子。若CNB与光子通过磁矩发生相互作用，该相互作用可在具有N^2增强的超海森堡极限下运行的单臂干涉仪中被揭示。
英文摘要
We study the interaction between light and non-relativistic cosmic neutrino background (CNB). We propose single arm laser interferometry with coherent laser source and two distinct squeezing operators to probe such interaction. We analyze the induced phase shift in four distinct quantum regimes of the interferometer operation: the standard quantum limit (SQL), the Heisenberg limit, super-Heisenberg limit with $N^{3/2}$ enhancement, and super-Heisenberg limit with $N^{2}$ enhancement where $N$ is the number of photons in the interferometer. We demonstrate that the $N^{2}$ super-Heisenberg enhancement has the potential to probe the magnetic moment down to $10^{-25}\, μ_{B}$ where $ μ_{B}$ is the Bohr magneton. If the CNB and photons interact via its magnetic moment, this interaction could be revealed in single arm interferometer operating at super-Heisenberg limit with $N^{2}$ enhancement.
