Effects of disorder and contacts on transport through graphene nanoribbons
A. Pieper, G. Schubert, G. Wellein +1
We study the transport of charge carriers through finite graphene structures. The use of numerical exact kernel polynomial and Green function techniques allows us to treat actual s…
Comment on "Anderson transition in disordered graphene"
J. Schleede, G. Schubert, H. Fehske
We comment on a recent letter by Amini et al. (EPL 87, 37002 (2009)) concerning the existence of a mobility edge in disordered graphene.
Particles as probes for complex plasmas in front of biased surfaces
R. Basner, F. Sigeneger, D. Loffhagen +3
An interesting aspect in the research of complex (dusty) plasmas is the experimental study of the interaction of micro-particles with the surrounding plasma for diagnostic purposes…
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…
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…
