Linked-cluster expansions for Rydberg atom arrays on the Kagome lattice — •Antonia Duft, Matthias Mühlhauser, Patrick Adelhardt, and Kai Phillip Schmidt — Friedrich-Alexander-Universität Erlangen-Nürnberg, Erlangen, Deutschland

We investigate a model of hardcore bosons on the links of a Kagome lattice subject to a long-range decaying van-der-Waals interaction. This model is known to be the relevant microscopic description of Rydberg atom arrays excited by a detuned laser field which has been realized in experiments recently. We apply high-order linked cluster expansions about different limits to investigate the quantum phase diagram. One particular interest is to find further evidence for the proposed topological phase in this quantum platform.
