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…
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…
Ionization of Sodium and Rubidium nS, nP and nD Rydberg atoms by blackbody radiation
I. I. Beterov, D. B. Tretyakov, I. I. Ryabtsev +2
Results of theoretical calculations of ionization rates of Rb and Na Rydberg atoms by blackbody radiation (BBR) are presented. Calculations have been performed for nS, nP and nD st…
