Near-field Hydrodynamics Disentangles Angular Correlations in Confined Active Suspensions
Changle Liao, Haruki Hayano, Yuto Uesugi +3
Spatial confinement profoundly impacts the transport and self-organization of active matter across diverse biological systems. While the collective orders in confined active matter…
Neural-Network-Assisted Boltzmann Approach for Dilute Microswimmer Suspensions
Haruki Hayano, Akira Furukawa, Kang Kim
We introduce a neural-network-assisted Boltzmann framework that learns the binary-collision map of microswimmers directly from data and uses it to evaluate collision integrals effi…
Anomalous rheology of puller-type microswimmer suspensions
Haruki Hayano, Akira Furukawa
We explore the mechanism underlying the anomalous rheology of puller-type microswimmer suspensions through direct hydrodynamic simulations. Puller-type swimmers generate contractil…
Heterogeneous Solvent Dissipation Coupled with Particle Rearrangement in Shear Thinning Non-Brownian Suspensions
Tomoharu Terayama, Akira Furukawa
Dense non-Brownian suspensions exhibit significant shear thinning, although a comprehensive understanding of the full scope of this phenomenon remains elusive. This study numerical…
Microrheology of active suspensions
Takahiro Kanazawa, Akira Furukawa
We study the microrheology of active suspensions through direct hydrodynamic simulations using model pusher-like microswimmers. We demonstrate that the friction coefficient of a pr…
