@article{Wildeboer2021TopologicalQM, title={Topological quantum many-body scars in quantum dimer models on the kagome lattice}, author={Julia S. Wildeboer and Alexander Seidel and N. S. Srivatsa and Anne Ellerup Nielsen and Onur Erten}, journal={Physical Review B}, year={2021} }

We utilize a general strategy to turn classes of frustration free lattice models into similar classes containing quantum many-body scars within the bulk of their spectrum while preserving much or all of the original symmetry. We apply this strategy to a well-known class of quantum dimer models on the kagome lattice with a large parameter space. We discuss that the properties of the resulting scar state(s), including entanglement entropy, are analytically accessible. Settling on a particular…
