Title: Magnetization Plateaus of SrCu{sub 2}(BO{sub 3}){sub 2} from a Chern-Simons Theory

Abstract

The antiferromagnetic Heisenberg model on the frustrated Shastry-Sutherland lattice is studied by a mapping onto spinless fermions carrying one quantum of statistical flux. Using a mean-field approximation these fermions populate the bands of a generalized Hofstadter problem. Their filling leads to the magnetization curve. For SrCu{sub 2}(BO{sub 3}){sub 2} we reproduce plateaus at 1/3 and 1/4 of the saturation moment and predict a new one at 1/2 . Gaussian fluctuations of the gauge field are shown to be massive at these plateau values.
