Engineered disorder in photonics

S Yu, CW Qiu, Y Chong, S Torquato, N Park - Nature Reviews Materials, 2021 - nature.com
Disorder, which qualitatively describes some measure of irregularities in spatial patterns, is
ubiquitous in many-body systems, equilibrium and non-equilibrium states of matter, network …

Hyperuniform states of matter

S Torquato - Physics Reports, 2018 - Elsevier
Hyperuniform states of matter are correlated systems that are characterized by an
anomalous suppression of long-wavelength (ie, large-length-scale) density fluctuations …

Photonic topological insulator in synthetic dimensions

E Lustig, S Weimann, Y Plotnik, Y Lumer, MA Bandres… - Nature, 2019 - nature.com
Topological phases enable protected transport along the edges of materials, offering
immunity against scattering from disorder and imperfections. These phases have been …

Higher-dimensional supersymmetric microlaser arrays

X Qiao, B Midya, Z Gao, Z Zhang, H Zhao, T Wu, J Yim… - Science, 2021 - science.org
The nonlinear scaling of complexity with the increased number of components in integrated
photonics is a major obstacle impeding large-scale, phase-locked laser arrays. Here, we …

Ensemble theory for stealthy hyperuniform disordered ground states

S Torquato, G Zhang, FH Stillinger - Physical Review X, 2015 - APS
It has been shown numerically that systems of particles interacting with isotropic “stealthy”
bounded long-ranged pair potentials (similar to Friedel oscillations) have classical ground …

Hyperuniformity and its generalizations

S Torquato - Physical Review E, 2016 - APS
Disordered many-particle hyperuniform systems are exotic amorphous states of matter that
lie between crystal and liquid: They are like perfect crystals in the way they suppress large …

Supersymmetric laser arrays

MP Hokmabadi, NS Nye, R El-Ganainy… - Science, 2019 - science.org
Scaling up the radiance of coupled laser arrays has been a long-standing challenge in
photonics. In this study, we demonstrate that notions from supersymmetry—a theoretical …

Nonlocal effective electromagnetic wave characteristics of composite media: Beyond the quasistatic regime

S Torquato, J Kim - Physical Review X, 2021 - APS
We derive exact nonlocal homogenized constitutive relations for the effective
electromagnetic wave properties of disordered two-phase composites and metamaterials …

Acoustic omni meta-atom for decoupled access to all octants of a wave parameter space

S Koo, C Cho, J Jeong, N Park - Nature communications, 2016 - nature.com
The common behaviour of a wave is determined by wave parameters of its medium, which
are generally associated with the characteristic oscillations of its corresponding elementary …

Broadband continuous supersymmetric transformation: a new paradigm for transformation optics

J Yim, N Chandra, X Feng, Z Gao, S Wu, T Wu, H Zhao… - eLight, 2022 - Springer
Transformation optics has formulated a versatile framework to mold the flow of light and
tailor its spatial characteristics at will. Despite its huge success in bringing scientific fiction …
