Fredholm Homotopies for Strongly-Disordered 2D Insulators
Alex Bols, Jeffrey Schenker, Jacob Shapiro
We study topological indices of Fermionic time-reversal invariant topological insulators in two dimensions, in the regime of strong Anderson localization. We devise a method to int…

Classification of equivariant quasi-local automorphisms on quantum chains
Alex Bols
We classify automorphisms on quantum chains, allowing both spin and fermionic degrees of freedom, that are moreover equivariant with respect to a local symmetry action of a finite…

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…
