"Dipolar Chiral Spin Liquids on stretched Kagome lattices"
The interplay between classical frustration and quantum fluctuations in spin systems can lead to topologically spin liquid states—seemingly featureless ground states that exhibit exotic properties such as long-range entanglement and fractionalized excitations. Recent developments in highly controllable and coherent quantum simulators offer a tantalizing opportunity to realize and probe these states. In this talk, we demonstrate how continuous control over geometry offers a new path for stabilizing the chiral spin liquid (CSL) state. Using large-scale tensor network calculations, we study a stretched (i.e., breathing) perturbation of a Kagome lattice with 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 and studying such states in the context of Rydberg and molecular tweezer array experiments.
