Second-order topological modes in two-dimensional continuous media
We present a symmetry-based scheme to create zero-dimensional (0D) second-order topological modes in continuous two-dimensional (2D) systems. We show that a metamaterial with a p6m-symmetric pattern exhibits two Dirac cones, which can be gapped in two distinct ways by deforming the pattern. Combinin...
