Velocity of an interface driven by an entropic force under shear flow
Yutaro Kado, Shin-ichi Sasa
Thermal fluctuations can drive an interface when bulk fluctuation amplitudes differ between two phases. We study how shear flow modifies this mechanism using a stochastic non-conse…
Pressure-drop localization and momentum insulation in liquid-gas coexistence Poiseuille flow
Naoko Nakagawa, Shin-ichi Sasa
We study pressure-driven Poiseuille flow of a one-component fluid between adiabatic plates in liquid-gas coexistence. The analysis uses Poiseuille flow and Fourier heat conduction…
Singularity of information flow at the Hopf bifurcation point
Kenshin Matsumoto, Shin-ichi Sasa
We investigate the singular behavior of information flow near the Hopf bifurcation point by analyzing the learning rate as a specific measure of information flow. We study the Brus…
Global thermodynamics for heat-conducting fluids under weak gravity
Naoko Nakagawa, Shin-ichi Sasa
We study liquid-gas coexistence under gravity and heat conduction from the viewpoint of global thermodynamics. We construct a variational free-energy function for the fixed-global-…
Anomalous Enhancement of Yield Strength due to Static Friction
Ryudo Suzuki, Takashi Matsushima, Tetsuo Yamaguchi +2
Friction is fundamental to mechanical stability across scales, from geological faults and architectural structures to granular materials and animal feet. We study the mechanical st…
Unifying renormalized and bare viscosity in two-dimensional molecular dynamics simulations
Kazuma Yokota, Masato Itami, Shin-ichi Sasa
Fluctuating hydrodynamics provides a framework connecting mesoscopic fluctuations with macroscopic transport behavior. To bridge mesoscopic and macroscopic transport from microscop…
