Dipolar Chiral Spin Liquids on stretched Kagome lattices

The interplay between classical frustration and quantum fluctuations in spin systems can lead to spin liquid states---seemingly featureless ground states that exhibit exotic properties such as long-range entanglement and fractionalized excitations. The recent development of highly controllable and coherent quantum simulators offers the tantalizing opportunity to realize and probe such states. In this talk, we demonstrate how the fine-tuned control over geometry can stabilize a chiral spin liquid (CSL) state. Using large scale tensor network calculations, we study a stretched (i.e. breathing) perturbation of a Kagome lattice of long-range dipolar interacting spins, and map out the associated phase diagram. We find a large region where the ground state is a gapped chiral spin liquid that spontaneously breaks time-reversal symmetry and hosts gapless edge modes. We conclude by discussing paths to generating such states in the context of Rydberg tweezer array experiments.
