Mixing induced by microswimmers as probed by mutual information
Yihong Shi, Yuto Hosaka, Andrej Vilfan +1
We investigate fluid mixing induced by microswimmers using mutual information as a global, information-theoretic measure of mixing efficiency. For a two-dimensional squirmer model…
Lateral hydrodynamics in supported membranes: The Evans-Sackmann model and its extensions
Yuto Hosaka, David Andelman, Shigeyuki Komura
We review the theoretical development and modern applications of the Evans-Sackmann hydrodynamic model for lateral transport in supported fluid membranes. We first cover the origin…
Analytical response functions for a compressible thin fluid layer with odd viscosity
Abdallah Daddi-Moussa-Ider, Yuto Hosaka, Shigeyuki Komura
Fluids composed of chiral active components can exhibit odd viscosity, a property that breaks time-reversal and parity symmetries. We investigate the hydrodynamic response to monop…
Self-phoretic colloids in chiral active fluids
Michalis Chatzittofi, Yuto Hosaka, Andrej Vilfan +1
Autonomous and driven transport in chiral active fluids have been shown to exhibit features that cannot be accommodated within the classical formulation of fluid mechanics, due to…
Dumbbell dimer dynamics in three-dimensional chiral fluids
Michalis Chatzittofi, Yuto Hosaka
We study the emergent orientational dynamics of a dumbbell dimer -- two asymmetric monomers connected by a linking spring -- in a three-dimensional chiral environment with odd visc…
Thermally driven two-sphere microswimmer with internal feedback control
Jun Li, Ziluo Zhang, Zhanglin Hou +4
We discuss the locomotion of a thermally driven elastic two-sphere microswimmer with internal feedback control that is realized by the position-dependent friction coefficients. In…
