Linear stability and viscoelastic response in weakly jammed frictional granular systems
Masanari Shimada, Yusuke Hara, Shihori Koyama +2
Granular particles typically feature contact friction, which gives rise to various nontrivial properties of granular materials. In this work, we investigate the linear stability of…
Colloidal Gelation with Non-Sticky Particles
Yujie Jiang, Ryohei Seto
Colloidal gels are widely applied in industry due to their rheological character -- no flow takes place below the yield stress. Such property enables gels to maintain uniform distr…
How Surface Roughness Affects the Interparticle Interactions at a Liquid Interface
Airi N. Kato, Yujie Jiang, Wei Chen +2
Shapes of colloids matter at liquid interfaces. We explore the interactions between rough-surfaced nanocolloids at the air--water interface through the compaction of monolayers exp…
Odd Viscosity in Chiral Passive Suspensions
Zhiyuan Zhao, Mingcheng Yang, Shigeyuki Komura +1
Prior studies have revealed that nonzero odd viscosity is an essential property for chiral active fluids. Here we report that such an odd viscosity also exists in suspensions of no…
Emergent Stripes of Active Rotors in Shear Flows
Zhiyuan Zhao, Boyi Wang, Shigeyuki Komura +3
The shear-induced self-organization of active rotors into stripy aggregates is studied by carrying out computational simulations. The rotors, modeled by monolayers of frictional sp…
The physics of dense suspensions
Christopher Ness, Ryohei Seto, Romain Mari
Dense suspensions of particles are relevant to many applications and are a key platform for developing a fundamental physics of out-of-equilibrium systems. They present challenging…
