Read full paper: here Disordered multihyperuniform many-particle systems are exotic amorphous states that allow exquisite color sensing capabilities due to their anomalous suppression of density fluctuations for distinct subsets of particles, as recently evidenced in photoreceptor mosaics in avian retina. Motivated by this biological finding, we present a statistical-mechanical model that rigorously achieves disordered multihyperuniform … Continue Reading “Disordered Multihyperuniformity Derived from Binary Plasmas” is published in Physical Review E.

read full paper: here We study the behavior of a classical two-component ionic plasma made up of nonadditive hard disks with additional logarithmic Coulomb interactions between them. Due to the Coulomb repulsion, long-wavelength total density fluctuations are suppressed and the system is globally hyperuniform. Short-range volume effects lead to phase separation or to heterocoordination for … Continue Reading “Disordered Hyperuniformity in Two-component Nonadditive Hard-disk Plasmas” is published in Physical Review E

Read the full paper: here Classical ground states (global energy-minimizing configurations) of many-particle systems are typically unique crystalline structures, implying zero enumeration entropy of distinct patterns (aside from trivial symmetry operations). By contrast, the few previously known disordered classical ground states of many-particle systems are all high-entropy (highly degenerate) states. Here we show computationally that … Continue Reading “Classical Many-Particle Systems with Unique Disordered Ground States” is published in Physical Review E.
