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…

Optical response of electrons in a random potential
Alexander Weisse, Gerald Schubert, Holger Fehske
Using our recently developed Chebyshev expansion technique for finite-temperature dynamical correlation functions we numerically study the AC conductivity of the Anderson mo…

Characterisation of Anderson localisation using distributions
A. Alvermann, G. Schubert, A. Weisse +2
We examine the use of distributions in numerical treatments of Anderson localisation and supply evidence that treating exponential localisation on Bethe lattices recovers the overa…
