The PairInteraction Toolkit for Modeling Rydberg Physics in Alkali and Alkaline-Earth-Like Atoms
This toolkit provides a unified theoretical framework for modeling interactions between Rydberg atoms, such as those in strontium or ytterbium. It combines Multi-Channel Quantum Defect Theory (MQDT) to describe atomic states with static electromagnetic Green’s tensors to calculate atom-atom and self-interaction energies. The resulting software allows researchers to accurately compute energy levels and interaction potentials for complex systems.
