A protocol for the preparation of chiral orbital Rydberg states in atoms is presented. It has been shown theoretically that using a suitable superposition of hydrogen wave functions, it is possible to construct a state with chiral signature, e.g. in the probability density or probability current density [1]. Circular Rydberg states can be generated and subsequently manipulated with tailored RF pulses under the influence of electric and magnetic fields, so that the desired chiral superposition of hydrogen-like states with corresponding phases can be prepared. The results are intended to be used for chiral discrimination [2] of molecules. The experimental progress is presented. This contribution is a continuation of the submission "Chirality Signatures in Atomic Rydberg States – Conditions and Symmetry Considerations".
