A space-adiabatic approach for bulk-defect correspondences in lattice models of topological insulators
Danilo Polo Ojito, Emil Prodan, Tom Stoiber
In space-adiabatic approaches one can approximate Hamiltonians that are modulated slowly in space by phase-space functions that depend on position and momentum. In this paper, we e…

On the K-theory of magnetic algebras: Iwatsuka case
Giuseppe De Nittis, Jaime Gomez, Danilo Polo Ojito
In the tight-binding approximation, an Iwatsuka magnetic field is modeled by a function on with constant, but distinct values in the two parts of the lattice separat…
