Magnetic chern bands and triplon Hall effect in an extended Shastry-Sutherland model
M. Malki, K. P. Schmidt
We study topological properties of one-triplon bands in an extended Shastry-Sutherland model relevant for the frustrated quantum magnet SrCu_2(BO_3)_2. To this end perturbative con…

Mutually attracting spin waves in the square-lattice quantum antiferromagnet
M. Powalski, K. P. Schmidt, G. S. Uhrig
The Heisenberg model for S=1/2 describes the interacting spins of electrons localized on lattice sites due to strong repulsion. It is the simplest strong-coupling model in condense…
