WebJan 24, 2024 · Not like resonant EIT-AT spectra, we realize the electric field measurement of the signal frequency from 2 GHz to 5 GHz using a single Rydberg state. A minimum detectable filed strength is down to ... WebThe extreme sensitivity of Rydberg states to electric fields is one reason we called them 'gentle' in the introduction. Sensitivity stems from the large spatial extent of the wave function of the weakly-bound valance electron. It was recognized early on that this sensitivity could be used to measure weak electric fields. WebHowever, the collisional instability of Rydberg atoms prevents a simple comparison to ground-state dipoles. Heteronuclear molecules polarize in a relatively weak electric field to have an electric dipole moment on the order of 1 debye. When normalized with respect to a typical a s, a dimensionless strength ɛ d d ≳ 1 0 is expected. pnc north ave kimball
