Bound-state Compton scattering of linearly polarized photons
Jonas Sommerfeldt, Nick M. Mayer, Anna Maiorova +4
We present a theoretical study of Compton scattering of X- and -rays by a -shell electron. Special attention is paid to the double-differential cross section and polarizatio…
Interaction of a Poincaré beam with optically polarized atoms in the presence of constant magnetic field
S. Ramakrishna, S. Fritzsche
Recent studies have highlighted the frequent applications of structured light modes in optically pumped atomic magnetometers. In this work, we theoretically explore how a Poincaré…
A distorted-wave approach to the elastic scattering of twisted electrons
A. L. Harris, S. Fritzsche
The elastic scattering of spinless vortex electrons on realistic target atoms has been investigated. In particular, expressions are derived in different approximations for the elas…
Quadratic Zeeman and Electric Quadrupole Shifts in Highly Charged Ions
Jan Gilles, Stephan Fritzsche, Lukas J. Spieà +2
Recent advances in high-precision spectroscopy of highly charged ions necessitate an understanding of energy shifts of ionic levels caused by external electric and magnetic fields.…
Interaction of vector light beams with atoms exposed to a time-dependent magnetic field
Shreyas Ramakrishna, Riaan P. Schmidt, Anton A. Peshkov +3
During recent years interest has been rising for applications of vector light beams towards magnetic field sensing. In particular, a series of experiments were performed to extract…
Hanle effect for lifetime determinations in the soft X-ray regime
Moto Togawa, Jan Richter, Chintan Shah +16
By exciting a series of transitions in helium-like nitrogen ions with linearly polarized mono…
