Density of States, Relaxation Dynamics, and Hopping Conductivity of Disordered Many-Electron Systems with Long-Range Correlation
We investigate the Coulomb glass as a model for the low-temperature behavior of polyanilines. It comprises many localized electrons subject to long-range Coulomb interaction in a random potential. Electron transfer takes place via hopping. We present Monte-Carlo results for the single-particle density of states. Hopping occurs between the many-particle states and is described by a rate equation which can be solved exactly yielding the relaxation dynamics and the conductivity.
