Localization of excitonic eigenfunctions in isotopically mixed naphthalene crystals

We present numerical calculations for the localization of excitonic eigenfunctions in substitutionally disordered naphthalene crystals. The distribution of the localization indices is evaluated by considering the off-diagonal disorder due to short-ranged triplet interactions. The transition from mol...

Description
Summary:We present numerical calculations for the localization of excitonic eigenfunctions in substitutionally disordered naphthalene crystals. The distribution of the localization indices is evaluated by considering the off-diagonal disorder due to short-ranged triplet interactions. The transition from molecular to crystal-like eigenfunctions occurs gradually as the trap concentration increases.
