The Role of Conical Intersections 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 study linear Rydberg chains perpendicular to each other in a 2D plane. Conical intersections then become relevant for the dynamics, without the need of a ring confinement [5]. We show that this feature leads to a highly nonadiabatic dynamic and an entanglement of motion.
