Three-dimensional three-photon Stark spectroscopy of a single Rb Rydberg atom in an ultrahigh-vacuum glass cell with eight electrodes
S. A. Spirin, E. A. Yakshina, A. K. Sologub +9
Quantum computing and quantum simulation with ultracold neutral atoms require Rydberg excitation of individual atoms in atomic arrays. Rydberg states are extremely sensitive to ext…
Superluminal two-color light in multiple Raman gain medium
V. Kudriašov, J. Ruseckas, A. Mekys +3
We investigate theoretically the formation of two-component light with superluminal group velocity in a medium controlled by four Raman pump fields. In such an optical scheme only…
Anomalies in radiation-collisional kinetics of Rydberg atoms induced by the effects of dynamical chaos and the double Stark resonance
N. N. Bezuglov, A. N. Klyucharev, A. A. Mihajlov +1
Radiative and collisional constants of excited atoms contain the matrix elements of the dipole transitions and when they are blocked one can expect occurring a number of interestin…
Autoionization of an ultracold Rydberg gas through resonant dipole coupling
T. Amthor, J. Denskat, C. Giese +4
We investigate a possible mechanism for the autoionization of ultracold Rydberg gases, based on the resonant coupling of Rydberg pair states to the ionization continuum. Unlike an…
Ionization of Rydberg atoms by blackbody radiation
I. I. Beterov, D. B. Tretyakov, I. I. Ryabtsev +3
We have studied an ionization of alkali-metal Rydberg atoms by blackbody radiation (BBR). The results of the theoretical calculations of ionization rates of Li, Na, K, Rb and Cs Ry…
Broadening and intensity redistribution in the Na() hyperfine excitation spectra due to optical pumping in the weak excitation limit
I. Sydoryk, N. N. Bezuglov, I. I. Beterov +5
Detailed analysis of spectral line broadening and variations in relative intensities of hyperfine spectral components due to optical pumping is presented. Hyperfine levels of sodiu…
