Read the full paper: here Link to the journal: here Hyperuniform states of matter are characterized by anomalous suppression of long-wavelength density fluctuations. While most of the interesting cases of disordered hyperuniformity are provided by complex many-body systems such as liquids or amorphous solids, classical spin chains with certain long-range interactions have been shown to … Continue Reading “Quantum phase transitions in long-range interacting hyperuniform spin chains in a transverse field” is published in Physical Review B

Read the full paper: here Link to the journal: here The hyperuniformity concept provides a unified means to classify all perfect crystals, perfect quasicrystals, and exotic amorphous states of matter according to their capacity to suppress large-scale density fluctuations. While the classification of hyperuniform point configurations has received considerable attention, much less is known about … Continue Reading “Characterizing the hyperuniformity of ordered and disordered two-phase media” is Published in Physical Review E

Read the full paper: here Link to the journal: here We derive exact expressions for effective elastodynamic properties of two-phase composites in the long-wavelength (quasistatic) regime via homogenized constitutive relations that are local in space. This is accomplished by extending the ‘strong-contrast’ expansion formalism that was previously applied to the static problem. These strong-contrast expansions … Continue Reading “Effective elastic wave characteristics of composite media” is Published in New Journal of Physics
