GOE statistics for Anderson models on antitrees and thin boxes in with deformed Laplacian
Christian Sadel
Sequences of certain finite graphs, antitrees, are constructed along which the Anderson model shows GOE statistics, i.e. a re-scaled eigenvalue process converges to the ${\rm Sine}…

Topological boundary invariants for Floquet systems and quantum walks
Christian Sadel, Hermann Schulz-Baldes
A Floquet systems is a periodically driven quantum system. It can be described by a Floquet operator. If this unitary operator has a gap in the spectrum, then one can define associ…

Spectral Theory of one-channel operators and application to absolutely continuous spectrum for Anderson type models
Christian Sadel
A one-channel operator is a self-adjoint operator on for some countable set with a rank 1 transition structure along the sets of a quasi-spherical…
