Entanglement transport and conical intersections in flexible Rydberg aggregates — •Sebastian Wüster, Sebastian Möbius, Cenap Ates, Alexander Eisfeld, and Jan-Michael Rost — MPI-PKS Dresden

Transfer of electronic excitations on chains of atoms or molecules is important in many areas of physics, such as photosynthetic light-harvesting or assemblies of Rydberg atoms in optical lattices. The electromagnetic interactions responsible for excitation propagation also exert mechanical forces on the chain, inducing motion of the constituents. In such a flexible aggregate, the atomic motion is typically entangled with the state of the electronic excitation. We consider a linear and a circular arrangement of Rydberg atoms on which a single electronic excitation propagates via dipole-dipole transitions, forming a Frenkel exciton.
