The effect of anisotropy on the absorption spectrum and the density of states of two-dimensional Frenkel exciton systems with Gaussian diagonal disorder
I. Avgin, D. L. Huber
On the optical absorption and the density of states of Frenkel exciton systems on square, rectangular, and triangular lattices with nearest-neighbor interactions and a Gaussian dis…
Accuracy of the coherent potential approximation for a one-dimensional array with a Gaussian distribution of fluctuations in the on-site potential
I. Avgin, D. L. Huber
We investigate the accuracy of the coherent potential approximation (CPA) for a one-dimensional array with nearest-neighbor interactions and a Gaussian distribution of fluctuations…
Localized exciton states in pi-conjugated polymers with finite torsion
I. Avgin, M. Winokur, D. L. Huber
We investigate localized exciton states in pi-conjugated polymers with finite torsion. The localized states are associated with a perturbed transfer integral for which the magnitud…
Scaling behavior of a one-dimensional correlated disordered electronic System
I Avgin
A one-dimensional diagonal tight binding electronic system with correlated disorder is investigated. The correlation of the random potential is exponentially decaying with distance…
Excitons in disordered polymers
I. Avgin, D. L. Huber
We investigate the effects of disorder on Frenkel excitons in disordered conjugated polymers with allowed rotations about single bonds. In these materials, the principal effect of…
Amplitude scaling behavior of low-energy Frenkel exciton chains with correlated off-diagonal disorder
I. Avgin, D. L. Huber
We report the amplitude scaling behavior of Frenkel exciton chains with nearest-neighbor correlated off-diagonal random interactions. The band center spectrum and its localization…
