Linear stability and viscoelastic response in weakly jammed frictional granular systems
Masanari Shimada, Yusuke Hara, Shihori Koyama +2
Granular particles typically feature contact friction, which gives rise to various nontrivial properties of granular materials. In this work, we investigate the linear stability of…
Statistical mechanics of fluids with hidden degrees of freedom
Masanari Shimada, Tetsuya J. Kobayashi
Although coarse-grained models have been widely used to explain exotic phenomena in complex fluids, such as droplet formation in living cells, these conventional approaches often f…
Fermionic theory of nonequilibrium steady states
Eric De Giuli, Masanari Shimada
As the quantification of metabolism, nonequilibrium steady states play a central role in living matter, but are beyond the purview of equilibrium statistical mechanics. Here we dev…
Universal Slow Dynamics of Chemical Reaction Networks
Masanari Shimada, Pegah Behrad, Eric De Giuli
Understanding the emergent behavior of chemical reaction networks (CRNs) is a fundamental aspect of biology and its origin from inanimate matter. A closed CRN monotonically tends t…
Instantaneous normal modes of glass-forming liquids during the athermal relaxation process of the steepest descent algorithm
Masanari Shimada, Kumpei Shiraishi, Hideyuki Mizuno +1
Understanding glass formation by quenching remains a challenge in soft condensed matter physics. Recent numerical studies on steepest descent dynamics, which is one of the simplest…
Gas-liquid phase separation at zero temperature: mechanical interpretation and implications for gelation
Masanari Shimada, Norihiro Oyama
The relationship between glasses and gels has been intensely debated for decades; however, the transition between these two phases remains elusive. To investigate a gel formation p…
Novel elastic instability of amorphous solids in finite spatial dimensions
Masanari Shimada, Hideyuki Mizuno, Atsushi Ikeda
Recently, progress has been made in the understanding of anomalous vibrational excitations in amorphous solids. In the lowest-frequency region, the vibrational spectrum follows a n…
Vibrational density of states of jammed packing: mean-field theory
Harukuni Ikeda, Masanari Shimada
Several mean-field theories predict that Hessian matrices of amorphous solids can be written by using the random matrix in the limit of the large spatial dimensions . M…
Spatial structure of unstable normal modes in a glass-forming liquid
Masanari Shimada, Daniele Coslovich, Hideyuki Mizuno +1
The phenomenology of glass-forming liquids is often described in terms of their underlying, high-dimensional potential energy surface. In particular, the statistics of stationary p…
Random quench predicts universal properties of amorphous solids
Masanari Shimada, Eric De Giuli
Amorphous solids display numerous universal features in their mechanics, structure, and response. Current models assume heterogeneity in mesoscale elastic properties, but require f…
Anharmonic properties of vibrational excitations in amorphous solids
Hideyuki Mizuno, Masanari Shimada, Atsushi Ikeda
Understanding the vibrational and thermal properties of amorphous solids is one of the most discussed and long-standing issues in condensed matter physics. Recent works have made s…
Low-frequency vibrations of jammed packings in large spatial dimensions
Masanari Shimada, Hideyuki Mizuno, Ludovic Berthier +1
Amorphous packings prepared in the vicinity of the jamming transition play a central role in theoretical studies of the vibrational spectrum of glasses. Two mean-field theories pre…
Vibrational spectrum derived from the local mechanical response in disordered solids
Masanari Shimada, Hideyuki Mizuno, Atsushi Ikeda
The low-frequency vibrations of glasses are markedly different from those of crystals. These vibrations have recently been categorized into two types: spatially extended vibrations…
Spatial structure of quasi-localized vibrations in nearly jammed amorphous solids
Masanari Shimada, Hideyuki Mizuno, Matthieu Wyart +1
The low-temperature properties of amorphous solids are widely believed to be controlled by low-frequency quasi-localized modes. What governs their spatial structure and density is…
Anomalous vibrational properties in the continuum limit of glasses
Masanari Shimada, Hideyuki Mizuno, Atsushi Ikeda
The low-temperature thermal properties of glasses are anomalous with respect to those of crystals. These thermal anomalies indicate that the low-frequency vibrational properties of…
