标题： Rydberg Atom Electric Field Sensors as Linear Time-invariant Systems

摘要： 在过去十年中，里德堡原子电场传感器作为射频通信、遥感和精密计量等领域中传统基于天线接收器的潜在替代品或补充品，一直受到研究。为了理解这些设备在各种应用场景中的潜在效用，至关重要的是开发能够准确预测关键性能指标（如瞬时带宽和动态范围）的模型。 然而，现有的数值模型需要求解一组大型耦合微分方程，这在计算上非常密集且耗时长。 我们提出了一种分析方法，可以用来推导冲激响应函数，与运动方程的时间相关积分相比，这种方法可以减少高达两个数量级的计算时间。 这种方法可用于快速评估里德堡传感器对各种波形的响应。 显示英文摘要

摘要： Over the past decade, Rydberg atom electric field sensors have been under investigation as potential alternatives or complements to conventional antenna-based receivers for select applications in RF communications, remote sensing, and precision metrology. To understand the potential utility of these devices for various use cases, it is crucial to develop models that accurately predict key performance metrics such as instantaneous bandwidth and dynamic range. However, existing numerical models require solving a large set of coupled differential equations that is computationally intensive and lengthy to solve. We present an analytic approach that can be used to derive an impulse response function that allows up to two orders-of-magnitude reduction in computation time compared to the full time-dependent integration of the equations of motion. This approach can be used to enable rapid assessments of the Rydberg sensor's response to various waveforms.
