Pressure shifts and broadening of electromagnetically induced transparency in rubidium Rydberg atoms

Rydberg atoms, with their unique properties and sensitivity to external fields, offer promising avenues for precise sensing of RF fields, blackbody radiation, and more. This project investigates the interaction between these atoms and different gases to develop rigorous standards for background gas pressure in atomic vapor cells. We report pressure shift and broadening parameters to characterize the interactions between Rydberg atoms and target gases under controlled conditions by monitoring an electromagnetically induced transparency signal. This research aims to contribute to the development of high-precision sensors based on atomic vapor cells with Rydberg atoms, including advanced microfabrication techniques. In particular, the results of this study aid in the diagnostics of poorly performing vapor cells.
