Title

Photonic quadrupole topological insulator using orbital-induced synthetic flux

Abstract
We demonstrate that mixing different orbitals can induce synthetic π-flux threading the lattice. As an experimental demonstration of such a concept, we realize a quadrupole topological insulator in a photonic lattice.
