Analysis
This paper explores a novel approach to microwave sensing using a cavity-free atomic system. The key innovation is the use of a Δ-type configuration, which allows for strong sensitivity to microwave field parameters without the constraints of a cavity. This could lead to more compact and robust atomic clocks and quantum sensors.

Reference
“The coherent population trapping (CPT) resonance exhibits a pronounced dependence on the microwave power and detuning, resulting in measurable changes in resonance contrast, linewidth, and center frequency.”
