Spectral correlations in systems undergoing a transition from periodicity to disorder
T. Dittrich, B. Mehlig, H. Schanz +3
We study the spectral statistics for extended yet finite quasi 1-d systems which undergo a transition from periodicity to disorder. In particular we compute the spectral two-point…
Universal spectral properties of spatially periodic quantum systems with chaotic classical dynamics
T. Dittrich, B. Mehlig, H. Schanz +1
We consider a quasi one-dimensional chain of N chaotic scattering elements with periodic boundary conditions. The classical dynamics of this system is dominated by diffusion. The q…
Signature of Chaotic Diffusion in Band Spectra
T. Dittrich, B. Mehlig, H. Schanz +1
We investigate the two-point correlations in the band spectra of spatially periodic systems that exhibit chaotic diffusion in the classical limit. By including level pairs pertaini…
Excitonic - vibronic coupled dimers: A dynamic approach
Bernd Esser, Holger Schanz
The dynamical properties of exciton transfer coupled to polarization vibrations in a two site system are investigated in detail. A fixed point analysis of the full system of Bloch…
Nonlinearity and trapping in excitation transfer: Dimers and Trimers.
Ivan Barvik, Bernd Esser, Holger Schanz
We study the interplay between nonlinearity in exciton transport and trapping due to a sink site for the dimer and the trimer with chain configuration by a numerical integration of…
Quantization of Sinai's Billiard - A Scattering Approach
Holger Schanz, Uzy Smilansky
We obtained the spectrum of the Sinai billiard as the zeroes of a secular equation, which is based on the scattering matrix of a related scattering problem. We show that this quant…
