On the Cover

Increasing the excitation intensity turns a tight-binding lattice of dielectric resonators from a trivial topological insulator (left) into a second-order topological insulator (right), with edge modes (light blue) and corner modes (red dots). Resonator couplings are linear (dark blue) or nonlinear (red lines).
