Heterogeneity and Low-Frequency Vibrations in Bidisperse Sphere Packings
Yusuke Hara, Hideyuki Mizuno, Atsushi Ikeda
In the jamming transition of monodisperse packings, spatial heterogeneity is irrelevant as the transition is described by mean-field theories. Here, we show that this situation dra…
Microrheology near jamming
Yusuke Hara, Hideyuki Mizuno, Atsushi Ikeda
The jamming transition is a nonequilibrium critical phenomenon, which governs characteristic mechanical properties of jammed soft materials, such as pastes, emulsions, and granular…
Arrhenius temperature dependence of the crystallization time of deeply supercooled liquids
Yuki Takaha, Hideyuki Mizuno, Atsushi Ikeda
Usually, supercooled liquids and glasses are thermodynamically unstable against crystallization. Classical nucleation theory (CNT) has been used to describe the crystallization dyn…
Non-phononic density of states of two-dimensional glasses revealed by random pinning
Kumpei Shiraishi, Hideyuki Mizuno, Atsushi Ikeda
The vibrational density of states of glasses is considerably different from that of crystals. In particular, there exist spatially localized vibrational modes in glasses. The densi…
