Using numerical as well as analytical tools of many-body physics, this project aims to advance our understanding of transport and excitations in prototypical frustrated quantum magnets which harbor unconventional states, such as spin liquids, or non-collinear, valence-bond, and topological phases. Specifically, we will perform (i) numerically exact studies of current correlation functions in Kitaev and ring-exchange ladders, (ii) an analysis of spin excitations and energy transport in non-collinear states as well as Kitaev spin-liquids in planar models for d5 iridates, and (iii) studies of elementary excitations and quantum phases of frustrated exciton-magnetic models for d4 iridates. The coupling to phonons, scattering from impurities, and the impact of external magnetic fields will be investigated.
