Symmetry-Based Classification of Chern Phases in Honeycomb Photonic Crystals
Rodrigo P. Câmara, Tatiana G. Rappoport, Mário G. Silveirinha
In this work, we develop a symmetry-based classification of Chern phases in honeycomb photonic crystals, considering arbitrary nonreciprocal couplings compatible with energy conser…

Non-Hermitian Photonic Spin Hall Insulators
Rodrigo P. Câmara, Tatiana G. Rappoport, Mário G. Silveirinha
Photonic platforms invariant under parity (), time-reversal (), and duality () can support topological phases analogous to those found in tim…
