Blending ordering within an uncorrelated disorder potential in families of 3D Lieb lattices preserves the macroscopic degeneracy of compact localized states and yields unconventional combinations of localized and delocalized phases—as shown in Liu et al. (Phys Rev B 106:214204, 2022). Danieli, Liu and Roemer proceed to reintroduce translation invariance in the system by further ordering the disorder, and discuss the spectral structure and eigenstates features of the resulting perturbed lattices. This strategy, herewith implemented in the 3D Lieb lattice, highlights order restoration as experimental pathway to engineer spectral and states features in disordered lattice structures in the pursuit of quantum storage and memory applications.

Two-dimensional random metal networks possess unique electrical and optical properties, such as almost total optical transparency and low sheet resistance. These properties are closely related to their disordered structure. In this work, Prof. Römer and colleagues from Dresden, Germany, give a detailed experimental and theoretical investigation of these plasmonic properties, revealing Anderson (disorder-driven) localized surface plasmon resonance. This could support the development of design rules for the underlying conduction networks, e.g., in order to further optimize design transparency for envisaged future applications as transparent electrodes.
