Effects of anisotropic dipole-dipole interactions on 3D flexible Rydberg aggegrates. — •Karsten Leonhardt, Sebastian Wüster, and Jan Michael Rost — Max Planck Institute for the Physics of Complex Systems

Exciton pulses transport excitation and entanglement adiabatically through flexible Rydberg aggregates [1], assemblies of highly excited light atoms, which are set into directed motion by resonant dipole-dipole interaction [1-4]. In the systems studied so far, the dipole-dipole interaction among the Rydberg atoms was completely isotropic, either enforced by geometry [2-4] or by external fields [5]. Here, we present the dynamics of exciton pulses, taking into account the spatial dependence of the dipole-dipole interaction. We also include fine-structure splitting into our model, which is relevant for Rb experiments.
