Building blocks of topological band theory for photonic crystals
Yoonseok Hwang, Vaibhav Gupta, Antonio Morales-Pérez +6
We derive a framework for classifying topological bands in three-dimensional photonic band structures, where the zero frequency polarization singularity implied by Maxwell's equati…

Stable Real-Space Invariants and Topology Beyond Symmetry Indicators
Yoonseok Hwang, Vaibhav Gupta, Frank Schindler +4
We introduce stable real-space invariants (SRSIs), topological invariants defined from adiabatic deformations between Wannier states, generalizing previously discovered local and c…
