Voltage and power-frequency electric field measurements with Rydberg-atom interferometry

Yingying Han, Changfa He, Zhenxiong Weng +3

We present a Rydberg-atom interferometry-based technique for voltage measurement between electrodes embedded in an atomic vapor cell, enabling the detection of weak voltages ($<0.1…

Phase-sensitive Rydberg-atom interferometry with Floquet electromagnetically induced transparency

Yingying Han, Changfa He, Peng Xu +3

We design a phase-sensitive Rydberg-atom interferometry by implementing Floquet electromagnetically induced transparency (FEIT). The FEIT mixes the sidebands of a Rydberg state ind…
