Cohesion-induced hysteresis and breakdown of marginal stability in jammed granular materials
Michio Otsuki, Kiwamu Yoshii, Hideyuki Mizuno
The dependence of mechanical properties on microscopic interactions remains a central problem in the physics of disordered solids near the jamming transition. We numerically and th…
Boson peak in covalent network glasses: Isostaticity and marginal stability
Hideyuki Mizuno, Tatsuya Mori, Giacomo Baldi +1
The boson peak (BP) stands as a key feature in understanding glasses and amorphous materials. It directly underlies their anomalous material properties, including thermal behaviors…
Enhanced collective vibrations in granular materials
Shihori Koyama, Norihiro Oyama, Hideyuki Mizuno +1
Granular materials are defined as collections of macroscopic dissipative particles. Although these systems are ubiquitous in our lives, the nature and the causes of their non-trivi…
Avalanche criticality emerges by thermal fluctuation in a quiescent glass
Yuki Takaha, Hideyuki Mizuno, Atsushi Ikeda
We report avalanche criticality of thermal relaxation in glassy systems after a rapid quench by molecular simulation. Our analysis of the energy landscape and the scaling reveals t…
Universal mechanism of shear thinning in supercooled liquids
Hideyuki Mizuno, Atsushi Ikeda, Takeshi Kawasaki +1
Soft glassy materials experience a significant reduction in viscosity when subjected to shear flow, known as shear thinning. This phenomenon is characterized by a power-law sc…
