Bound states and plateaus: Magnetization behavior of the maple leaf lattice — •Jannis Seufert, Pratyay Ghosh, Tobias Müller, and Ronny Thomale — Julius-Maximilians-Universität, Würzburg, Germany

Recently, the maple leaf lattice equipped with a Heisenberg-Hamiltonian was shown to exhibit an analytically exact antiferromagnetic dimer ground state analogous to the better known Shastry-Sutherland model. Anticipating that its even stronger frustration will lead to both familiar and exotic magnetic behavior, we present the calculation of magnetization plateaus in the maple leaf model with Ising- and Heisenberg-spins. For the latter, this is achieved within a perturbation theory of magnetic excitations incorporating triplet-triplet interactions and correlated hopping, which promotes the emergence of bound states.
