Title: Shastry-Sutherland magnets: a new playground for realizing Dirac
spin liquids

Abstract: The iconic Shastry-Sutherland lattice on which a system of
antiferromagnetically interacting Heisenberg spins lends itself to an exact
solution, represents a cornerstone of in the theory of frustrated
magnetism. The last few years have witnessed a cascade of new material
systems based on rare-earth ions of Pr and Yb ions which serve as excellent
candidate quantum spin liquid materials. Concurrently, there is mounting
evidence from theory that a quantum spin liquid regime exists in the model
antiferromagnet. In this talk, I will try to reconcile experiment and
theory by presenting the case of a Dirac spin liquid which promises to
explain a wealth of observed features in experiment and is consistent with
the findings from unbiased numerical approaches.
