Study of the localization-delocalization transition for phonons via transfer matrix method techniques
Sebastian D. Pinski, Rudolf A. Roemer
We use a transfer-matrix method to study the localization properties of vibrations in a `mass and spring' model with simple cubic lattice structure. Disorder is applied as a box-di…

Compressibility stripes for mesoscopic quantum Hall samples
Christoph Sohrmann, Rudolf A. Roemer
We numerically investigate the interplay of disorder and electron-electron interactions in the integer quantum Hall effect. In particular, we focus on the behaviour of the electron…

Universal level-spacing statistics in quasiperiodic tight-binding models
Uwe Grimm, Rudolf A. Roemer, Michael Schreiber +1
We study statistical properties of the energy spectra of two-dimensional quasiperiodic tight-binding models. The multifractal nature of the eigenstates of these models is corrobora…
