Non-Hermitian Boundary State Engineering in Anomalous Floquet Topological Insulators
Bastian Höckendorf, Andreas Alvermann, Holger Fehske
In Hermitian topological systems, the bulk-boundary correspondence strictly constraints boundary transport to values determined by the topological properties of the bulk. We demons…

Topological invariants for Floquet-Bloch systems with chiral, time-reversal, or particle-hole symmetry
Bastian Höckendorf, Andreas Alvermann, Holger Fehske
We introduce -valued bulk invariants for symmetry-protected topological phases in dimensional driven quantum systems. These invariants adapt the -invariant,…
