“Hyperuniformity of Quasicrystals” was published in Physical Review B Categories News Author chmadmin Read full paper: here Hyperuniform systems, which include crystals, quasicrystals, and special disordered systems, have attracted considerable recent attention, but rigorous analyses of the hyperuniformity of quasicrystals have been lacking because the support of the spectral intensity is dense and discontinuous. We employ the integrated spectral intensity \(Z(k)\) to quantitatively characterize the hyperuniformity of quasicrystalline … Continue Reading “Hyperuniformity of Quasicrystals” was published in Physical Review B
“Percolation of disordered jammed sphere packings” was published in Journal of Physics A: Mathematical and Theoretical Categories News Author chmadmin Read the full paper: We determine the site and bond percolation thresholds for a system of disordered jammed sphere packings in the maximally random jammed state, generated by the Torquato–Jiao algorithm. For the site threshold, which gives the fraction of conducting versus non-conducting spheres necessary for percolation, we find \(p_c = 0.3116(3)\), consistent with the … Continue Reading “Percolation of disordered jammed sphere packings” was published in Journal of Physics A: Mathematical and Theoretical
