Dynamics of particle lane formation in confined viscoelastic fluids under shear
Hiroto Yokoyama, Masanori Honda, Rinya Miyakawa +5
Simple shear flow can induce flow-aligned chain formation of particles suspended in viscoelastic fluids. Although this phenomenon has been reported for decades, direct {\it in situ…
Arrested coarsening in active colloidal suspensions driven by nonreciprocal electrohydrodynamic interactions
Shoma Hara, Masazumi Okada, Keisuke Kittaka +5
Nonreciprocal interactions have recently attracted growing interest in nonequilibrium physics. In particular, breaking action-reaction symmetry has been proposed as a mechanism for…
Pattern transition of flow dynamics in a highly water-absorbent granular bed
Kojiro Otoguro, Kiwamu Yoshii, Yutaka Sumino
An aqueous sodium chloride solution was injected at a controlled rate into a granular bed in a quasi-two-dimensional cell. The granular bed was made of dried, highly water-absorben…
Deformation and motion of giant unilamellar vesicles loaded with gold nanoparticles driven by induced charge electro-osmotic flow
Kotaro Nakazawa, Yoshinori Sonoyama, Yutaka Sumino
A vesicle is a spherical structure composed of a phospholipid bilayer that is used as a container for chemicals, both it in vivo and it in vitro systems. In both cases, the vesicle…
Stochastic heat differences between many-particle and density field descriptions
Takuya Saito, Yutaka Sumino
This article investigates spatiotemporally discrete or continuous stochastic descriptions, where we focus on differences in heat naturally defined between the particle level and th…
