Negative thermal Hall conductance in a two-dimer Shastry-Sutherland model with a π-flux Dirac triplon
We introduce an effective two-dimer tight-binding model for the family of Shastry-Sutherland models with geometrically tunable triplon excitations. The Rashba pseudospin-orbit coupling induced by the tilted external magnetic field leads to elementary excitations having nontrivial topological propert...
