Read the full paper: here Link to the journal: here Disordered stealthy hyperuniform materials exhibit the statistical isotropy of a liquid combined with some of the structural properties of a crystal—including homogeneity, suppressed density fluctuations at large length scales, bounded holes, and a structure factor \(S(k)\) that vanishes for a finite range of wave vectors, … Continue Reading “Structural and physical properties of gyromorphs and disordered stealthy hyperuniform media” Published in Physical Review B

Read the full paper: here Link to the journal: here Pulverizing together a Cr\(^\text{II}\) perovskite, (BA)\(_2\)Cr\(^\text{II}\)Cl\(_4\), and a Cr\(^\text{III}\) double perovskite, (BA)\(_4\)Ag\(^\text{I}\)Cr\(^\text{III}\)Cl\(_8\), at room temperature affords a new layered perovskite alloy incorporating three different metal ions in each layer: (BA)\(_8\)(Ag\(^\text{I}\)Cr\(^\text{III}\))Cr\(^\text{II}\)\(_2\)Cl\(_{16}\) (BA = \(n\)-butylammonium). The magnetic ground state of this alloy is a spin glass (freezing … Continue Reading “A Mosaic Layered Halide-Perovskite Spin Glass: Mechanochemical Alloying of a Ferromagnet and a Paramagnet” Published in ACS Central Science

Read the full paper: here Link to the journal: here The time-dependent diffusion spreadability \(\mathcal{S}(t)\) is a powerful dynamical probe of the microstructure of two-phase heterogeneous media across length scales [Torquato, S., \emph{Phys. Rev. E.}, 104 054102 (2021)]. The spreadability can be exactly represented as a certain functional of the spectral density \(\tilde{\chi}_{_V}(\mathbf{k})\), where \(\bf … Continue Reading “Precise determination of the long-time asymptotics of the diffusion spreadability of two-phase media” Published in Physical Review E
