Unconstrained Chern-Simons theory for the geometrically frustrated spin compound SrCu$_2$(BO$_3$)$_2$
ORAL
Abstract
We show that an unconstrained Chern-Simons theory -- where the local densities are determined in a self-consistent manner -- correctly reproduces the sequence of magnetization plateaus recently observed in the geometrically frustrated spin compound SrCu$_2$(BO$_3$)$_2$ in an external magnetic field. The theory predicts that at the plateaus, the triplets are arranged in stripe patterns which is consistent with NMR experiments at and close to the 1/8 plateau.
