Quantum beats in optical activity and weak interactions

Abstract Tunnelling back and forth between the degenerate isomers of a simple optically active molecule may lead to observable oscillations as a function of time in the optical activity of a properly prepared material. This effect can cause oscillations on the order of seconds or longer and would provide a remarkable example of quantum phenomena on a macroscopic time scale. Such a system is sensitive to extremely small energies and could reveal the presence of the weak interaction as it lifts the degeneracy of the isomers. This may occur at the level of around 10 −15 eV. The presence of the weak interaction would be revealed by oscillation of the optical activity around a non-zero value. We point out that the traditional view of the origin of the stability of optical isomers must be modified due to the presence of the weak interaction.
