Absolutely Continuous Edge Spectrum of Hall Insulators on the Lattice
Alex Bols, Albert H. Werner
The presence of chiral modes on the edges of quantum Hall samples is essential to our understanding of the quantum Hall effect. In particular, these edge modes should support balli…
Chiral Floquet systems and quantum walks at half period
C. Cedzich, T. Geib, A. H. Werner +1
We classify chiral symmetric periodically driven quantum systems on a one-dimensional lattice. The driving process is local, can be continuous or discrete in time, and we assume a…
Anderson localization for electric quantum walks and skew-shift CMV matrices
C. Cedzich, A. H. Werner
We consider the spectral and dynamical properties of one-dimensional quantum walks placed into homogenous electric fields according to a discrete version of the minimal coupling pr…
Quantum walks: Schur functions meet symmetry protected topological phases
C. Cedzich, T. Geib, F. A. Grünbaum +3
This paper uncovers and exploits a link between a central object in harmonic analysis, the so-called Schur functions, and the very hot topic of symmetry protected topological phase…
