Inferring stealthy hyperuniform correlations from quantum transport
Natanael C. Costa, Mauro S. Ferreira, Caio Lewenkopf +4
Stealthy hyperuniform disordered systems exhibit strongly suppressed long-wavelength fluctuations, producing correlated disorder with unusual consequences for wave propagation. A c…
Analysis of Conjectural Improvements to Minkowski's Lower Bound on the Sphere Packing Density
Carlo Vanoni, Alan Guo, Salvatore Torquato
Torquato and Stillinger conjectured an exponential improvement of Minkowski's classical lower bound on the maximal density of sphere packings in high-dimensional Euclidean space $\…
Two-dimensional stealthy hyperuniform polycrystalline disk packings
Carlo Vanoni, Paul J. Steinhardt, Salvatore Torquato
Polycrystals consist of grains of local crystalline order separated by grain boundaries. Their structure is not hyperuniform, even though perfect crystals are, because polycrystals…
Resonance Proliferation Across Localization Transitions
Carlo Vanoni, David M. Long, Anushya Chandran
Models of many-body localization (MBL) exhibit slow numerical drifts towards delocalization with increasing system size, for which no satisfactory theory exists. Numerics indicates…
Effective delocalization in the one-dimensional Anderson model with stealthy disorder
Carlo Vanoni, Jonas Karcher, Mikael C. Rechtsman +3
We study analytically and numerically the Anderson model in one dimension with "stealthy" disorder, defined as having a power spectrum that vanishes in a continuous band of wave nu…
Quantifying when hyperuniformity of a many-particle system leads to uniformity across length scales
Carlo Vanoni, Paul J. Steinhardt, Salvatore Torquato
Hyperuniform systems are distinguished by an unusually strong suppression of large-scale density fluctuations and, consequently, display a high degree of uniformity at the largest…
