Polarization-Dependent Disappearance of a Resonance Signal -- Indication for Optical Pumping in a Storage Ring?
W. Nörtershäuser, A. Surzhykov, R. Sánchez +10
We report on laser spectroscopic measurements on Li ions in the experimental storage ring ESR at the GSI Helmholtz Centre for Heavy Ion Research. Driving the $2s\,^3\!{S}_1\;(F…
Symmetry breaking and phase transitions in Bose-Einstein condensates with spin-orbital-angular-momentum coupling
Y. Duan, Y. M. Bidasyuk, A. Surzhykov
Theoretical study is presented for a spinor Bose-Einstein condensate, whose two components are coupled by copropagating Raman beams with different orbital angular momenta. The inve…
Rayleigh scattering of a linearly polarized light: scenario of the complete experiment
A. V. Volotka, A. Surzhykov, S. Fritzsche
The process of the elastic scattering of photons on atoms, known as the Rayleigh scattering, is investigated. Expressing the scattering observables in terms of the electric and mag…
Vacuum polarization and finite nuclear size effects in the two-photon decay of hydrogen-like ions
J. Sommerfeldt, R. A. Müller, A. V. Volotka +2
The total two-photon decay rate of hydrogen-like ions is studied using relativistic quantum electrodynamics. In particular, we analyse how finite nuclear size and QED vacuum polari…
Resonant sequential two-photon ionization of atoms by twisted and plane-wave light
V. P. Kosheleva, V. A. Zaytsev, R. A. Müller +2
We study the resonant sequential two-photon ionization of neutral atoms by a combination of twisted- and plane-wave light within a fully relativistic framework. In particular, the…
Generalized excitation of atomic multipole transitions by twisted light modes
S. A. -L. Schulz, A. A. Peshkov, R. A. Müller +5
A theoretical study is performed for the excitation of a single atom localized in the center of twisted light modes. Here we present the explicit dependence of excitation rates on…
