Exciton hamiltonian
WebExcitons. Excitons refer to electronic excited states that are not localized to a particular molecule. But beyond that there are many flavors. We will concentrate on Frenkel excitons, which refer to excited states in which the excited electron and the corresponding hole (or … http://mukamel.ps.uci.edu/publications/pdfs/384.pdf
