Topology of quantum coherence network in singlet fission: mapping exciton states into real space and the dislocation induced three dimensional manifolds

Abstract

The understanding of the global structure of quantum coherence network in the coupled multistate systems is of great importance for the development of emerging quantum technologies such as quantum control and quantum materials design. Here we study the topology of quantum coherence network of a typical singlet exciton fission system by mapping the exciton states into the crystal structures in real space. The defects in crystals could lead to changes in the topological structures, and also fission dynamics. In particular, we demonstrate that the dislocation induced three dimensional manifolds, which differs from its lower dimensional counterparts globally, could generate exotic global structures, such as chiral spirals, and modulate singlet fission substantially. The findings may shed lights on the new possibilities of engineering effective structures for fission materials.
