What Do Deep Neural Networks Find in Disordered Structures of Glasses?
Norihiro Oyama, Shihori Koyama, Takeshi Kawasaki
Glass transitions are widely observed in various types of soft matter systems. However, the physical mechanism of these transitions remains {elusive}, despite years of ambitious re…
Aging or DEAD: origin of the non-monotonic response to weak self-propulsion in active glasses
Natsuda Klongvessa, Christophe Ybert, Cécile Cottin-Bizonne +2
Among amorphous states, glass is defined by relaxation times longer than the observation time. This nonergodic nature makes the understanding of glassy systems an involved topic, w…
Relaxation dynamics and long-time tails explain shear-induced diffusion of soft athermal particles near jamming
Kuniyasu Saitoh, Takeshi Kawasaki
We numerically study shear-induced diffusion of soft athermal particles in two dimensions. The Green-Kubo (GK) formula is applicable to the shear-induced diffusion coefficient, whe…
Anomalous fluctuations in homogeneous fluid phase of active Brownian particles
Yuta Kuroda, Hiromichi Matsuyama, Takeshi Kawasaki +1
Giant number fluctuations (GNF) are an anomaly universally observed in active fluids with polar or nematic order. In this paper, we show that GNF arise in the fluid phase of active…
Geometrical properties of mechanically annealed systems near the jamming transition
Hiromichi Matsuyama, Mari Toyoda, Takumi Kurahashi +3
Geometrical properties of two-dimensional mixtures near the jamming transition point are numerically investigated using harmonic particles under mechanical training. The configurat…
Emergent elasticity linked to topological phase transitions controlled via molecular chirality and steric anisotropy
Kyohei Takae, Takeshi Kawasaki
Self-organisation into spatially modulated structures has different nature from phase transition into uniform states. Skyrmions and half-skyrmions (merons) are representatives of s…
