Scalable Methods for Electronic Excitation and Optical Responses of Nanostructures: Mathematics to Algorithms to Observables

Electronic and other elementary excitations play a central role in understanding and controlling the properties of nanostructures. Yet at present, simulation methods are inadequate to describe these properties, because they don’t scale well or don’t provide the necessary accuracy. In this project, theoretical methods to treat elementary excitations will be developed that merge molecular and solid-state methods to address the special challenges of large disordered nanostructures. This project adapts molecular methods to treat large numbers of particles, and solid state methods to treat systems with disorder. Underlying all of the simulation methods are common mathematical kernels from numerical linear algebra and optimization theory that are being addressed by close interactions between application scientists and mathematicians. The project will advance modeling of optical response, charge transport, coupling between radiation and nanomotion in nanostructures of all kinds, as well as providing broader impacts from the improvements in electronic structure simulation methodology and fundamental algorithms in applied mathematics.
