Minimum scaling model and exact exponents for the Nambu-Goldstone modes in the Vicsek Model
Harukuni Ikeda
We investigate the scaling behavior of Nambu-Goldstone (NG) modes in the ordered phase of the Vicsek model, introducing a phenomenological equation of motion (EOM) incorporating a…
Control parameter dependence of fluctuation near jamming
Harukuni Ikeda
The fluctuations of the physical quantities play a central role to characterize the critical phenomena. Here, we report that the nature of the fluctuation highly depends on the con…
Testing mean-field theory for jamming of non-spherical particles: Contact number, gap distribution, and vibrational density of states
Harukuni Ikeda
We perform numerical simulations of the jamming transition of non-spherical particles in two dimensions. In particular, we systematically investigate how the physical quantities at…
Non-Affine Displacements Below Jamming under Athermal Quasi-Static Compression
Harukuni Ikeda, Koji Hukushima
Critical properties of frictionless spherical particles below jamming are studied using extensive numerical simulations, paying particular attention to the non-affine part of the d…
Note: Relaxation time below jamming
Harukuni Ikeda
Like other critical phenomena, the jamming transition accompanies the divergence of the relaxation time . A recent numerical study of frictionless spherical particles proves tha…
Jamming below upper critical dimension
Harukuni Ikeda
Extensive numerical simulations in the past decades proved that the critical exponents of the jamming of frictionless spherical particles remain unchanged in two and three dimensio…
Jamming with tunable roughness
Harukuni Ikeda, Carolina Brito, Matthieu Wyart +1
We introduce a new model to study the effect of surface roughness on the jamming transition. By performing numerical simulations, we show that for a smooth surface, the jamming tra…
Infinitesimal asphericity changes the universality of the jamming transition
Harukuni Ikeda, Carolina Brito, Matthieu Wyart
The jamming transition of non-spherical particles is fundamentally different from the spherical case. Non-spherical particles are hypostatic at their jamming points, while isostati…
Effect of particle exchange on the glass transition of binary hard spheres
Harukuni Ikeda, Francesco Zamponi
We investigate the replica theory of the liquid-glass transition for a binary mixture of large and small additive hard spheres. We consider two different ansätze for this problem:…
Multiple glass transitions and higher order replica symmetry breaking of binary mixtures
Harukuni Ikeda, Kunimasa Miyazaki, Hajime Yoshino +1
We extend the replica liquid theory in order to describe the multiple glass transitions of binary mixtures with large size disparities, by taking into account the two-step replica…
Note: A replica liquid theory of binary mixtures
Harukuni Ikeda, Kunimasa Miyazaki, Atsushi Ikeda
It has been known that the binary replica liquid theory (RLT) is inconsistent with its one-component counterpart; In the limit that all atoms are identical, the configurational ent…
One-dimensional Kac model of dense amorphous hard spheres
Harukuni Ikeda, Atsushi Ikeda
We introduce a new model of hard spheres under confinement for the study of the glass and jamming transitions. The model is an one-dimensional chain of the -dimensional boxes ea…
