Journal ArticleDOI
Radiative electron capture into high-Z few-electron ions: Alignment of the excited ionic states
TL;DR: In this paper, a unified formalism for the description of radiative electron capture into excited states of heavy, few-electron ions and their subsequent decay, including a full account of manyelectron effects and higher-order multipoles of the radiation field, is presented.
Journal ArticleDOI
Entanglement dynamics of three-qubit states in noisy channels
Michael Siomau,Stephan Fritzsche +1 more
TL;DR: In this article, the authors studied the entanglement dynamics of the three-qubit system with the help of the lower bound for concurrence and showed that the W-state is more resistant to decoherence than the GHZ state.
Journal ArticleDOI
Algebraic tools for dealing with the atomic shell model. I. Wavefunctions and integrals for hydrogen-like ions ✩
TL;DR: The D IRAC program which has been developed originally for studying the properties and dynamical behavior of the (hydrogen-like) ions is presented and a set of MAPLE procedures is provided for the Coulomb wave and Green’s functions by applying the (wave) equations from both, the nonrelativistic and relativistic theory.
Journal ArticleDOI
Radiative capture of twisted electrons by bare ions
Oliver Matula,Armen G. Hayrapetyan,Valery G. Serbo,Andrey Surzhykov,Stephan Fritzsche,Stephan Fritzsche +5 more
TL;DR: In this article, the angular and polarization distributions of twisted electron beams with bare ions were derived on the basis of the density matrix formalism and non-relativistic Schrodinger theory.
Journal ArticleDOI
Ab initio calculations of the 2 p 3 / 2 − 2 p 1 / 2 fine-structure splitting in boronlike ions
A. N. Artemyev,A. N. Artemyev,V. M. Shabaev,I. I. Tupitsyn,G. Plunien,Andrey Surzhykov,Stephan Fritzsche,Stephan Fritzsche +7 more
TL;DR: In this paper, the authors performed ab initio QED calculations of the fine-structure splitting along the boron isoelectronic sequence for all ions with $17.
