Theory of electrolytes including steric, attractive, and hydration interactions
Ryuichi Okamoto, Kenichiro Koga, Akira Onuki
We present a continuum theory of electrolytes composed of a waterlike solvent and univalent ions. First, we start with a density functional for the coarse-grained solvent,…
Theory of nonionic hydrophobic solutes in mixture solvent: Solvent-mediated interaction and solute-induced phase separation
Ryuichi Okamoto, Akira Onuki
We present a theory of nonionic solutes in a mixture solvent composed of water-like and alcohol-like species. First, we show relationship among the solvation chemical potential, th…
A three-sphere microswimmer in a structured fluid
Kento Yasuda, Ryuichi Okamoto, Shigeyuki Komura
We discuss the locomotion of a three-sphere microswimmer in a viscoelastic structured fluid characterized by typical length and time scales. We derive a general expression to link…
Dynamics of a bilayer membrane with membrane-solvent partial slip boundary conditions
Kento Yasuda, Ryuichi Okamoto, Shigeyuki Komura +1
We discuss the dynamics of a bilayer membrane with partial slip boundary conditions between the monolayers and the bulk fluid. Using Onsager's variational principle to account for…
Thermal and active fluctuations of a compressible bilayer vesicle
T. V. Sachin Krishnan, Kento Yasuda, Ryuichi Okamoto +1
We discuss thermal and active fluctuations of a compressible bilayer vesicle by using the results of hydrodynamic theory for vesicles. Coupled Langevin equations for the membrane d…
Thermally Driven Elastic Micromachines
Yuto Hosaka, Kento Yasuda, Isamu Sou +2
We discuss the directional motion of an elastic three-sphere micromachine in which the spheres are in equilibrium with independent heat baths having different temperatures. Even in…
