Accurate Modeling of Rydberg Atoms and Their Interactions: Theory and Implementation in PairInteraction
Johannes Mögerle, Frederic Hummel, Alicia Keil +8
Rydberg atoms provide a powerful platform for exploring strongly interacting quantum systems, both in free space and in structured electromagnetic environments, with growing applic…
Engineering Rydberg-pair interactions in divalent atoms with hyperfine-split ionization thresholds
Frederic Hummel, Sebastian Weber, Johannes Moegerle +5
Quantum information processing with neutral atoms relies on Rydberg excitation for entanglement generation. While the use of heavy divalent or open-shell elements, such as strontiu…
observation of non-polar to strongly polar atom-ion collision dynamics
Moritz Berngruber, Daniel J. Bosworth, Oscar A. Herrera-Sancho +8
The onset of collision dynamics between an ion and a Rydberg atom is studied in a regime characterized by a multitude of collision channels. These channels arise from coupling betw…
Kato's theorem and ultralong-range Rydberg molecules
Matthew T. Eiles, Frederic Hummel
We consider non-adiabatic coupling in the "trilobite"-like long-range Rydberg molecules created by perturbing degenerate high- Rydberg states with a ground-state atom. Due to…
Non-adiabatic interaction effects in the spectra of ultralong-range Rydberg molecules
Rohan Srikumar, Frederic Hummel, Peter Schmelcher
Ultralong-range Rydberg molecules (ULRM) are highly imbalanced bound systems formed via the low-energy scattering of a Rydberg electron with a ground-state atom. We investigate for…
Synthetic dimension-induced conical intersections in Rydberg molecules
Frederic Hummel, Matthew T. Eiles, Peter Schmelcher
We observe a series of conical intersections in the potential energy curves governing both the collision between a Rydberg atom and a ground-state atom and the structure of Rydberg…
