Coupling between a magnon and a triplon lattice in SeCuO3
The Cu-based quantum magnet hosts three types of magnetic excitations : triplons, magnons and spinons. Their behaviour has been nicely explained by a model based on two decoupled magnetic sublattices. The first one is formed by non-interacting dimers while LRO emerges on the second one. However, previous INS measurements showed multiple evidence of a weak coupling between both sublattices, which would be suppressed by the strong dimer interaction within a dimer unit. This energy scale difference effectively reduces the dimensionality of the system. The present experiment proposes to characterise the interaction responsible for the coupling between both sublattices by mapping out the dimer excitation at low- and high-temperature. It would then open the way to a theoretical treatment of multi-type excitations systems.
