Instability of isolated triplet excitations on the Shastry-Sutherland lattice (SSL)
A. Fledderjohann, K. -H. Muetter
Configurations of singlets and triplets on the SSL have been proposed in the literature as variational ground states of the Shastry-Sutherland model at fixed magnetization M. We pr…

Magnetic order in the Shastry-Sutherland model
A. Fledderjohann, K. -H. Muetter
The ground state properties of the Shastry-Sutherland model in the presence of an external field are investigated by means of variational states built up from unpaired spins (monom…
