Chiral edge dynamics of ultracold erbium atoms in a synthetic Hall system — Roberto Vittorio Röll, Arif Warsi Laskar, •Franz Richard Huybrechts, and Martin Weitz — Universität Bonn, Deutschland

The study of non-trivial topological phases of matter offers opportunities to produce platforms for interesting physics and plays an important role in the advancement of applications in the realm of quantum computing and information. Research on topologically protected edge states is currently being conducted due to their robustness with regards to smooth changes in the system's geometry. Here we report on the observation of chiral edge dynamics with an ultracold atomic erbium system in a synthetic 2D Hall ribbon, which is spanned by one internal and one external degree of freedom of the atoms. The topological nature of the system is confirmed by observing both closed and skipping orbits, and by determining the local Chern marker.
