Geometric bulk-edge correspondence for -topological insulators
Alexis Drouot, Jacob Shapiro, Xiaowen Zhu
Fermionic time-reversal-invariant insulators in two dimensions--class AII in the Kitaev table--come in two topological phases. These phases are characterized by a -va…
Edge spectrum for truncated -insulators
Alexis Drouot, Jacob Shapiro, Xiaowen Zhu
Fermionic time-reversal-invariant insulators in two dimensions -- class AII in the Kitaev table -- come in two different topological phases. These are characterized by a $\mathbb{Z…
Absolutely continuous spectrum for truncated topological insulators
Alexis Drouot, Jacob Shapiro, Xiaowen Zhu
We show that if a topological insulator is truncated along a curve that separates the plane in two sufficiently large regions, then the edge system admits absolutely continuous spe…
The bulk-edge correspondence for curved interfaces
Alexis Drouot, Xiaowen Zhu
The bulk-edge correspondence is a condensed matter theorem that relates the conductance of a Hall insulator in a half-plane to that of its (straight) boundary. In this work, we ext…
