It has been shown theoretically [1] that by combining a superposition of Hydrogenic wavefunctions in combination with appropriately adjusted phases, the resulting electronic state can show chiral properties. We are proposing a protocol for experimentally creating those states in a ultra-cold cloud of Rubidium atoms by exciting into a circular Rydberg state and subsequently generating a superposition of different states of almost maximum ℓ and mℓ. The results are aimed to be used for chiral discrimination [2] of molecules. Optimized parameters will be determined to maximize the chiral sensitivity.
