Quadrupole topological photonic crystals
Most higher order topological phases are realized by emulations of tight binding models. Extending these concepts to continuum theories requires the identification of invariants describing the bulk multipole order. Here the authors realize the analog of quadrupole order for a gyromagnetic photonic c...

description | Most higher order topological phases are realized by emulations of tight binding models. Extending these concepts to continuum theories requires the identification of invariants describing the bulk multipole order. Here the authors realize the analog of quadrupole order for a gyromagnetic photonic crystal. |
