Chirality in the electronic structure of bound systems is regularly associated with the three-dimensional spatial distribution of nuclei in molecules. But also in atomic systems, states with chiral signatures can be formed as superpositions of the achiral eigenstates of hydrogenic systems, either due to parity-violating effects [1] or through careful state preparation [2].
We use linear combinations of hydrogenic functions as model systems to identify the conditions for the quantum numbers and relative phases that lead to chirality in such a superposition. Moreover, we show which minimal selection of states enable which diverse chiral signatures and report simple rules for the composition of states with specific chiral signatures. Our model system most naturally applies to Rydberg states, especially in atoms, but can also further the understanding of chirality in molecules and chiral potentials. This topic is continued in the submission "Chirality Signatures in Atomic Rydberg States -- Experimental State Preparation".
