Optical response of many-polaron systems
G. Wellein, A. R. Bishop, M. Hohenadler +2
Exact results for the density of states and the ac conductivity of the spinless Holstein model at finite carrier density are obtained combining Lanczos and kernel polynomial method…

Optical absorption and activated transport in polaronic systems
G. Schubert, G. Wellein, A. Weiße +2
We present exact results for the optical response in the one-dimensional Holstein model. In particular, by means of a refined kernel polynomial method, we calculate the ac and dc e…
