Abstract
We perform Zeeman spectroscopy on a Rydberg electromagnetically induced transparency (EIT) system in a room-temperature Cs vapor cell, in magnetic fields up to 50 Gauss. The magnetic interactions of the |6S1/2 Fg = 4> ground, |6P3/2 Fe = 5> intermediate, and |33S1/2> Rydberg states that form the ladder-type EIT system are in the linear Zeeman, quadratic Zeeman, and the Paschen-Back regimes, respectively. We explain the dependence of Rydberg EIT spectra on the magnetic field and polarization. The asymmetry of the EIT spectra, which is caused by the quadratic Zeeman effect of the intermediate state, becomes paramount in magnetic fields ≥40 Gauss. We investigate the interplay between Rydberg EIT, which reduces photon scattering, and optical pumping, which relies on photon scattering. We employ a quantum Monte Carlo wave-function approach to quantitatively model the spectra and their asymmetry behavior. Simulated spectra are in good agreement with the experimental data.
Highlights
Rydberg atoms, highly excited atoms with principal quantum numbers n >> 1 [1], possess extraordinary properties, such as long lifetime and strong dipole-dipole interaction
To interpret the rich structure that we measure in our experimental Rydberg Electromagnetically induced transparency (EIT) spectra in magnetic fields, it is essential to employ a quantitative model that accounts for the exact dependence of the optical couplings on magnetic quantum numbers and beam polarization, atom decay, optical pumping among the magnetic sublevels, the nonlinear Zeeman effect, and Rydberg-level dephasing
We have performed Rydberg EIT spectroscopy in a cesium room-temperature vapor cell when an axial magnetic field in the range between 0 and 50 Gauss is applied
Summary
Highly excited atoms with principal quantum numbers n >> 1 [1], possess extraordinary properties, such as long lifetime and strong dipole-dipole interaction These offer considerable potential for applications in quantum information processing [2,3], nonlinear optics [4,5] and non-equilibrium phenomena [6,7,8]. Their strong response to microwave electric fields makes these atoms attractive for performing traceable microwave measurements [9,10]. Linear and quadratic Zeeman splittings affect EIT line positions and optical pumping rates, and have a pronounced effect on the steady-state and dynamic behavior. Simulation results are in good agreement with our experiments and afford further insight into the optical-pumping dynamics
