Local physics of magnetization plateaux in the Shastry-Sutherland model
L. Isaev, G. Ortiz, J. Dukelsky
We address the physical mechanism responsible for the emergence of magnetization plateaux in the Shastry-Sutherland model. By using a hierarchical mean-field approach we demonstrat…

Phase diagram of the Heisenberg antiferromagnet with four-spin interactions
L. Isaev, G. Ortiz, J. Dukelsky
We study the quantum phase diagram of the Heisenberg planar antiferromagnet with a subset of four-spin ring exchange interactions, using the recently proposed heirarchical mean-fie…
