论文摘要
基于Rydberg原子的射频天线原则上可以达到任何传统的电线天线的敏感性，尤其是在需要很长的电线以适应生长波长的较长的频率下。本文介绍了Rydberg天线敏感性的详细理论研究，阐明参数制度可能会累积地导致2--3个数量级灵敏度的提高。特别感兴趣的是提议补偿原子运动诱导的多普勒扩散的三重射手设置。这种设置确实被证明是有利的，但这仅仅是因为它们恢复了对\ emph {预期}多普勒限制值的敏感性，从而消除了显着的额外额外差减少。
Radio frequency antennas based on Rydberg atoms can in principle reach sensitivities beyond those of any conventional wire antenna, especially at lower frequencies where very long wires are needed to accommodate the growing wavelength. This paper presents a detailed theoretical investigation of Rydberg antenna sensitivity, elucidating parameter regimes that could cumulatively lead to 2--3 orders of magnitude sensitivity increase. Of special interest are three-laser setups proposed to compensate for atom motion-induced Doppler spreading. Such setups are in indeed shown to be advantageous, but only because they restore sensitivity to the \emph{expected} Doppler-limited value, removing significant additional off-resonance reductions.
