Conical Intersections and exitation transport in flexible Rydberg aggregates — •Karsten Leonhardt, Sebastian Wüster, and Jan Michael Rost — Max Planck Institute for the Physics of Complex Systems

Transport of electronic excitation is a very important mechanism in nature, e.g. Photosynthesis [1]. It was shown that in linear flexible Rydberg aggregates [2] localized excitons connects the electronic excitation and entanglement transport with atomic motion [3,4]. Here we show that Rydberg systems also allow reflection of the excitation transport by fixing the positions of the last atoms in the aggregate. Further we extend the setup to a 2D arrangement to get access to Conical intersections. We use this feature to create entanglement of atomic motion.
