Sub-diffusive wave transport and weak localization transition in three-dimensional stealthy hyperuniform disordered systems
Fabrizio Sgrignuoli, Salvatore Torquato, Luca Dal Negro
The purpose of this work is to understand the fundamental connection between structural correlations and light localization in three-dimensional (3D) open scattering systems of fin…
Aperiodic bandgap structures for enhanced quantum two-photon sources
Luca Dal Negro, Yuyao Chen, Sean Gorsky +1
In this paper we propose a novel approach to enhance the efficiency of the two-photon spontaneous emission process that is driven by the multifractal optical mode density of photon…
Wave transport and localization in prime number landscapes
Luca Dal Negro, David Taylor Henderson, Fabrizio Sgrignuoli
In this paper, we study the wave transport and localization properties of novel aperiodic structures that manifest the intrinsic complexity of prime number distributions in imagina…
Structural entropy and spatial decay of quasimodes in Vogel spirals
Marcus Prado, Fabrizio Sgrignuoli, Yuyao Chen +2
We investigate the spatial decay and temporal localization properties of quasimodes (i.e., scattering resonances) of two-dimensional Vogel spirals, composed of deterministic, aperi…
Hyperuniformity and wave localization in pinwheel scattering arrays
F. Sgrignuoli, L. Dal Negro
We investigate the structural and spectral properties of deterministic aperiodic arrays designed from the statistically isotropic pinwheel tiling. By studying the scaling of the cu…
