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…

Anomalous phonon dispersion near yielding in athermal crystals
Fumiaki Nakai, Michio Otsuki, Kuniyasu Saitoh +1
Vibrational properties of ordered athermal solids near yielding remain poorly understood. We show that yielding in a sheared crystal is governed not by a single localized instabili…
