Local Density Fluctuation Governs the Divergence of Viscosity underlying Elastic and Hydrodynamic Anomalies in a 2D Glass-Forming Liquid
Hayato Shiba, Takeshi Kawasaki, Kang Kim
If a liquid is cooled rapidly to form a glass, its structural relaxation becomes retarded, producing a drastic increase in viscosity. In two dimensions, strong long-wavelength fluc…
Monte Carlo study of the frame, fluctuation and internal tensions of fluctuating membranes with fixed area
Hayato Shiba, Hiroshi Noguchi, Jean-Baptiste Fournier
Three types of surface tensions can be defined for lipid membranes: the internal tension, , conjugated to the real membrane area in the Hamiltonian, the mechanical frame tension…
Mechanical properties and microdomain separation of fluid membranes with anchored polymers
Hao Wu, Hayato Shiba, Hiroshi Noguchi
The entropic effects of anchored polymers on biomembranes are studied using simulations of a meshless membrane model combined with anchored linear polymer chains. The bending rigid…
Structure formation of surfactant membranes under shear flow
Hayato Shiba, Hiroshi Noguchi, Gerhard Gompper
Shear-flow-induced structure formation in surfactant-water mixtures is investigated numerically using a meshless-membrane model in combination with a particle-based hydrodynamics s…
Relationship between bond-breakage correlations and four-point correlations in heterogeneous glassy dynamics: Configuration changes and vibration modes
Hayato Shiba, Takeshi Kawasaki, Akira Onuki
We investigate the dynamic heterogeneities of glassy particle systems in the theoretical schemes of bond breakage and four-point correlation functions. In the bond-breakage scheme,…
Spatiotemporal heterogeneity of local free volumes in highly supercooled liquid
Hayato Shiba, Takeshi Kawasaki
We discuss the spatiotemporal behavior of local density and its relation to dynamical heterogeneity in a highly supercooled liquid by using molecular dynamics simulations of a bina…
Measurement of the bending rigidity and spontaneous curvature of fluid membranes in simulations
Hayato Shiba, Hiroshi Noguchi
Several numerical methods for measuring the bending rigidity and the spontaneous curvature of fluid membranes are studied using two types of meshless membrane models. The bending r…
Jammed Particle Configurations and Dynamics in High-Density Lennard-Jones Binary Mixtures in Two Dimensions
Hayato Shiba, Akira Onuki
We examine the changeover in the particle configurations and the dynamics in dense Lennard-Jones binary mixtures composed of small and large particles. By varying the composition a…
Plastic deformations in crystal, polycrystal, and glass in binary mixtures under shear: Collective yielding
Hayato Shiba, Akira Onuki
Using molecular dynamics simulation, we examine the dynamics of crystal, polycrystal, and glass in a Lennard-Jones binary mixture composed of small and large particles in two dimen…
Plastic flow in polycrystal states in a binary mixture
Toshiyuki Hamanaka, Akira Onuki
Using molecular dynamics simulation we examine dynamics in sheared polycrystal states in a binary mixture containing 10% larger particles in two dimensions. We find large stress fl…
Elastic Convection in Vibrated Viscoplastic Fluids
Hayato Shiba, Jori Ruppert-Felsot, Yoshiki Takahashi +3
We observe a new type of behavior in a shear thinning yield stress fluid: freestanding convection rolls driven by vertical oscillation. The convection occurs without the constraint…
