We present measurements of the hyperfine structure (HFS) of the $n{P}_{J}$ Rydberg states for a large range of principal quantum number $n$ $(n=41--55)$ employing microwave spectroscopy in an ultracold cesium Rydberg ensemble. A microwave field with $30\text{\ensuremath{-}}\textmu{}\mathrm{s}$ duration couples the $nS\ensuremath{\rightarrow}nP$ transition, yielding a narrow linewidth spectroscopy that approaches the Fourier limit, which allows us to resolve the hyperfine structure of $n{P}_{J}$ states. By analyzing the hyperfine splittings of $n{P}_{J}$ states, we determine the magnetic dipole HFS coupling constant ${\overline{A}}_{\mathrm{HFS},{P}_{1/2}}=3.760(26)$ GHz for the ${P}_{1/2}$ state, and ${\overline{A}}_{\mathrm{HFS},{P}_{3/2}}=0.718(27)$ GHz and ${\overline{B}}_{\mathrm{HFS},{P}_{3/2}}=\ensuremath{-}0.084(102)$ GHz for the ${P}_{3/2}$ state. Systematic uncertainties caused by stray electromagnetic field, microwave field power, and Rydberg interaction are analyzed. This measurement is significant for the investigation of Rydberg electrometry and quantum simulation with dipole interaction involving the $n{P}_{J}$ state.We present measurements of the hyperfine structure (HFS) of the $n{P}_{J}$ Rydberg states for a large range of principal quantum number $n$ $(n=41--55)$ employing microwave spectroscopy in an ultracold cesium Rydberg ensemble.

Hyperfine structure of nP1/2 Rydberg states in Rb85

Ryan Cardman, Georg A. Raithel

We measure the hyperfine structure of $n{P}_{1/2}$ Rydberg states for $n=$ 42, 43, 44, and 46 using mm-wave spectroscopy on an ensemble of laser-cooled $^{85}\mathrm{Rb}$ atoms. Systematic uncertainties in our measurement from the Zeeman splittings induced by stray magnetic fields and dipole-dipole interactions between two Rydberg atoms are factored in with the obtained statistical uncertainty. Our final measurement of the $n{P}_{1/2}$ hyperfine coupling constant is ${A}_{\text{HFS}}=1.443(31)$ GHz. This measurement is useful for studies of long-range Rydberg molecules, Rydberg electrometry, and quantum simulation with dipole-dipole interactions involving $n{P}_{1/2}$ atoms.We measure the hyperfine structure of $n{P}_{1/2}$ Rydberg states for $n=$ 42, 43, 44, and 46 using mm-wave spectroscopy on an ensemble of laser-cooled $^{85}\mathrm{Rb}$ atoms.
