A fresh computational approach to atomic structures, processes and cascades — •Stephan Fritzsche — Helmholtz Institute, Jena, Germany — Friedrich-Schiller University Jena

The recent years have seen an increasing demand for accurate atomic computations. Apart from the traditional fields of astro- and plasma physics, accurate atomic data are needed today in various emerging areas, such as laser spectroscopy, quantum optics and metrology, x-ray lithography, or even in material science, to name just a few. -- In this contribution, I present a new (Julia) code for modelling atomic properties and processes. To this end, a high-level toolbox has been designed (and already implemented to a sizable extent) for dealing more efficiently with complex systems. Here, I shall introduce these tools and explain by simple examples how they help provide accurate theoretical predictions and may serve for (requests from) the spectroscopy of atoms and multiply-charged ion and in various fields elsewhere.
