Pre-yielding mechanical response near the jamming transition
Hidemasa Bessho, Takeshi Kawasaki, Kunimasa Miyazaki
The mechanical and rheological properties of jammed packings of frictionless particles under shear strain remain not fully understood, even when the strain amplitude is very small…
Potential energy landscape picture of zero-temperature avalanche criticality governing dynamics in supercooled liquids
Norihiro Oyama, Yusuke Hara, Takeshi Kawasaki +1
Supercooled liquids are metastable states realized by suppressing crystallization below the melting temperature. While it is well established that their dynamics slow down dramatic…
Zero-temperature Avalanche Criticality Governing Dynamical Heterogeneity in Supercooled Liquids
Norihiro Oyama, Yusuke Hara, Takeshi Kawasaki +1
In supercooled liquids, mesoscale mobile and immobile domains are ubiquitously observed, a phenomenon known as dynamical heterogeneity. Extensive studies have established that the…
Hyperuniformity near jamming transition over a wide range of bidispersity
Duc T. Dam, Takeshi Kawasaki, Atsushi Ikeda +1
We numerically investigate hyperuniformity in two-dimensional frictionless jammed packings of bidisperse systems. Hyperuniformity is characterized by the suppression of density flu…
Singular density correlations in chiral active fluids in three dimensions
Yuta Kuroda, Takeshi Kawasaki, Kunimasa Miyazaki
We investigate density fluctuations in three-dimensional chiral active fluids by using a simple model of helical self-propelled particles. Helical motion is generated by a constant…
Crystallization of Chiral Active Brownian Particles at Low Densities
Kangeun Jeong, Yuta Kuroda, Yuki Asatani +2
Chiral active matter is a variant of active matter systems in which the motion of the constituent particles violates mirror symmetry. In this letter, we simulate two-dimensional ch…
Effects of curvature on growing films of microorganisms
Yuta Kuroda, Takeshi Kawasaki, Andreas M. Menzel
To provide insight into the basic properties of emerging structures when bacteria or other microorganisms conquer surfaces, it is crucial to analyze their growth behavior during th…
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 sca…
Long-range translational order and hyperuniformity in two-dimensional chiral active crystal
Yuta Kuroda, Takeshi Kawasaki, Kunimasa Miyazaki
We numerically study two-dimensional athermal chiral active particles at high densities. The particles in this system perform the circular motion with frequency . We show that t…
Scale Separation of Shear-induced Criticality in Glasses
Norihiro Oyama, Takeshi Kawasaki, Kang Kim +1
In a sheared steady state, glasses reach a nonequilibrium criticality called yielding. In this letter, we report that the qualitative nature of this nonequilibrium critical phenome…
