Figure 2 | Comparison between a twisted lattice cavity and a singulonic cavity. Left: schematic and field distribution (in logarithmic scale) of a twisted lattice cavity; Right: schematic and field distribution (in logarithmic scale) of a singulonic cavity. The power-law divergence of the narwhal-shaped wavefunction enhances the electric field intensity by more than six orders of magnitude in the deep-subwavelength region.
