The diversity of three-dimensional photonic crystals
Nature Communications, 2021 Photonic crystals have a range of desirable properties for manipulating light. Here, the authors calculate and use the photonic band gap for thousands of such crystals to examine heuristics for their design and predict new photonic crystal structures.

Quadrupole topological photonic crystals [PDF]
Nature Communications, 2020 AbstractQuadrupole topological phases, exhibiting protected boundary states that are themselves topological insulators of lower dimensions, have recently been of great interest. Extensions of these ideas from current tight binding models to continuum theories for realistic materials require the identification of quantized invariants describing the bulk
