Anomalous statistics in the Langevin equation with fluctuating diffusivity: from Brownian yet non-Gaussian diffusion to anomalous diffusion and ergodicity breaking

Takuma Akimoto, Jae-Hyung Jeon, Ralf Metzler +3

Diffusive motion is a fundamental transport mechanism in physical and biological systems, governing dynamics across a wide range of scales -- from molecular transport to animal for…

Effect of flow kinematics on extensional viscosity of dilute polymer solutions

Yusuke Koide, Takato Ishida, Takashi Uneyama +1

We investigate the effect of flow kinematics on the extensional viscosity of dilute polymer solutions by conducting dissipative particle dynamics simulations under uniaxial, planar…

Information-Theoretical Approach to Relaxation Time Distribution in Rheology: Log-Normal Relaxation Spectrum Model

Takashi Uneyama

The relaxation modulus of a viscoelastic fluid can be decomposed into multiple Maxwell models and characterized by the relaxation spectrum for the relaxation time. It is empiricall…

Radius of Gyration in Shear Gradient Direction Governs Steady Shear Viscosity of Rouse-Type Model

Takashi Uneyama

We analyze the stress tensor and the gyration tensor of an unentangled polymer melt under flow by using a Rouse-type single chain model. We employ the bead-spring type single chain…

Coarse-Grained Simulation Model for Crystalline Polymer Solids by using Breakable Bonds

Takashi Uneyama

We propose a highly coarse-grained simulation model for crystalline polymer solids with crystalline lamellar structures. The mechanical properties of a crystalline polymer solid ar…
