Description

The quantum magnet SrCu2(BO3)2 is a physical realisation of the Shastry-Sutherland model – a two-dimensional square lattice, solved to have a ground state of singlets on diagonal bonds. Recent theoretical work suggests that the material should play host to a topological phase of triplons, which may manifest a thermal Hall effect. However, within the measured experimental resolution, we report that there is no thermal Hall signal of the predicted magnitude. This is possibly due to triplon-triplon interactions playing a more significant role than anticipated in the temperature range under investigation. (author)
