Query: Orthogonal flexible Rydberg aggregates   We study the link between atomic motion and exciton transport in flexible
Rydberg aggregates, assemblies of highly excited light alkali atoms, for which
motion due to dipole-dipole interaction becomes relevant. In two
one-dimensional atom chains crossing at a right angle adiabatic exciton
transport is affected by a conical intersection of excitonic energy surfaces,
which induces controllable non-adiabatic effects. A joint exciton/motion pulse
that is initially governed by a single energy surface is coherently split into
two modes after crossing the intersection. The modes induce strongly different
atomic motion, leading to clear signatures of non-adiabatic effects in atomic
density profiles. We have shown how this scenario can be exploited as an
exciton switch, controlling direction and coherence properties of the joint
pulse on the second of the chains [K.~Leonhardt {\it et al.}, Phys.~Rev.~Lett.
{\bf 113} 223001 (2014)]. In this article we discuss the underlying complex
dynamics in detail, characterise the switch and derive our isotropic
interaction model from a realistic anisotropic one with the addition of a
magnetic bias field.
