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…
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…
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…
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…
