Topological states in individual molecules
In a combined effort of scanning-probe experiments and computational theory we investigate the low-energy spectrum of spin and charge excitations in broad classes of polyradicals immobilized on insulating substrates. Of interest is the interplay of zero-energy modes of topological origin with bond-length patterns and the resulting possibility of soliton creation, manipulation and detection. A particular focus will be the generation of excitons, their localization in real space and impact on chemical reactivity.
