Prediction for a Dirac Spin Liquid in a Rydberg Tweezer Array
POSTER
Abstract
Tweezer arrays of neutral Rydberg atoms are an increasingly capable and versatile experimental platform for studying quantum many-body physics. One alluring target for such experiments is the analog simulation of exotic phases of quantum matter. In this work, we numerically investigate a long-range antiferromagnetic XY spin model that naturally arises in tweezer arrays: the effective spin is encoded in a pair of Rydberg states, and the atoms interact through dipolar exchange. Large-scale iDMRG calculations reveal the ground state of this model on the kagome lattice to be a gapless Dirac spin liquid. We show how this highly-entangled phase can be adiabatically prepared from a simple paramagnet initial state. We also explore several avenues for experimentally characterizing the Dirac spin liquid, including detection of edge modes and Friedel oscillations by quantum gas microscopy.
