Effects of interface regularity on the bulk-edge correspondence in continuum photonic systems
Matthew Frazier, Guillaume Bal
In this study we analyze the topological invariants and edge states of transverse magnetic wave propagation in continuum photonic systems at a finite-width interface between two gy…

Quantum anomalous Hall phases in gated rhombohedral graphene
Matthew Frazier, Guillaume Bal
We consider a coupled system of Dirac operators that models spin- and valley-polarized gated rhombohedral graphene (RHG) with an arbitrary number of layers. We classify all quantum…

Topological edge states of continuous Hamiltonians
Matthew Frazier, Guillaume Bal
This paper concerns the topological classification of continuous Hamiltonians that find applications in biased cold plasmas and photonics. Besides a magnetic bias, the Hamiltonians…
