This work pushes atomistic excitonic calculations toward the 10-million-atom scale using scalable numerical strategies. It demonstrates that excitonic properties of truly large nanostructures can be treated without abandoning atomistic resolution.
Keywords: linear scaling
Main result: excitonic calculations at the 10-million-atom scale become computationally feasible with a linear-scaling atomistic framework. This opens realistic many-body modeling for structures far beyond traditional limits.
