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 an electron density and probability current distribution that has chiral nature [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. A method to produce such Rydberg states is outlined and their properties including time evolution are discussed. Necessary conditions for quantum numbers of superposition states have been derived analytically. The results are aimed to be used for chiral discrimination [2] of molecules.
