Title: Transport Phase Diagram and Anderson Localization in Hyperuniform Disordered Photonic Materials,
Abstract: Hyperuniform disordered photonic materials (HDPM) are spatially correlated
dielectric structures with unconventional optical properties. They can be
transparent to long-wavelength radiation while at the same time have isotropic
band gaps in another frequency range. This phenomenon raises fundamental
questions concerning photon transport through disordered media. While optical
transparency is robust against recurrent multiple scattering, little is known
about other transport regimes like diffusive multiple scattering or Anderson
localization. Here we investigate band gaps, and we report Anderson
localization in two-dimensional stealthy HDPM using numerical simulations of
the density of states and optical transport statistics. To establish a unified
view, we propose a transport phase diagram. Our results show that, depending
only on the degree of correlation, a dielectric material can transition from
localization behavior to a bandgap crossing an intermediate regime dominated by
tunneling between weakly coupled states.
