Opacity predictions in plasmas under stellar conditions using deep learning
Djamel Benredjem, Jean-Christophe Pain
The aim of this work is to predict the opacity of plasmas under stellar conditions. We focus on iron and nickel, as these elements have been extensively investigated both theoretic…
Precision spectroscopy of the fine and hyperfine structures of high molecular Rydberg-Stark states: Metrology of molecular hydrogen ions
Ioana Doran, Leon Jeckel, Maximilian Beyer +2
The Stark effect in autoionizing high- Rydberg states decouples the Rydberg electron from the ion core through mixing with core-nonpenetrating high- states. The Ryd…
Quantum study of ultracold atom-ion excitation exchange
Tibor Jónás, Romain Vexiau, Nadia Bouloufa-Maafa +3
The quantum dynamics of ultracold collisions between rubidium atoms and excited metastable strontium ions is treated in the laboratory frame, enlightening the importance of the cou…
The Stark effect in molecular Rydberg states: Calculation of Rydberg-Stark manifolds of H and D including fine and hyperfine structures
Ioana Doran, Leon Jeckel, Maximilian Beyer +2
We present a general theoretical treatment and calculations of the fine and hyperfine structures in the spectra of high- molecular Rydberg states in static uniform electric fiel…
Strongly dipolar molecular Bose-Einstein condensates: From few- to many-body physics
Andreas Schindewolf, Jens Hertkorn, Ian Stevenson +8
Recent advances in molecular cooling have enabled the realization of strongly dipolar Bose--Einstein condensates (BECs) of molecules, and BECs of many different molecular species m…
Atomic Observables Induced by Cosmic Fields
Sebastian Lahs, Daniel Comparat, Fiona Kirk +1
The existence of cosmic fields made from yet unknown light bosons is predicted in many extensions to the Standard Model. They are especially of interest as possible constituents of…
