The wellspring of all phases of the kagome quantum antiferromagnet
Dr. Bryan Clark (host Seidel), Department of Physics, University of Illinois at Urbana-Champaign
Frustrated quantum magnets are a central theme in condensed matter physics due to the richness of their phase diagrams. They support a panoply of phases including various ordered states and topological phases. In this talk we explain the source of this richness. We report on the discovery of a Hamiltonian which has an exponentially degenerate ground state and show how it appears to source many of the phases on the kagome lattice including the enigmatic spin-liquid.
