Elucidation of the Correlation between Molecular Conformation and Shear Viscosity of Polymer Melts under Steady-State Shear Flow
Yuhi Sakamaki, Shota Goto, Kang Kim +1
The rheological behavior of polymer melts is strongly influenced by parameters such as chain length, chain stiffness, and architecture. In particular, shear thinning, characterized…
Graph neural network-based structural classification of glass-forming liquids and its interpretation via self-attention mechanism
Kohei Yoshikawa, Kentaro Yano, Shota Goto +2
Glass-forming liquids exhibit slow dynamics below their melting temperatures, maintaining an amorphous structure reminiscent of normal liquids. Distinguishing microscopic structure…
Persistent Homology Reveals the Role of Stiffness in Forming Topological Glasses in Dense Solutions of Ring Polymers
Shota Goto, Takenobu Nakamura, Davide Michieletto +2
Ring polymers are characterized by topology-specific entanglements called threadings. In the limit of large rings, it is conjectured that a "topological glass" should emerge due to…
Unraveling the glass-like dynamic heterogeneity in ring polymer melts: From semi-flexible to stiff chain
Shota Goto, Kang Kim, Nobuyuki Matubayasi
Ring polymers are an intriguing class of polymers with unique physical properties, and understanding their behavior is important for developing accurate theoretical models. In this…
Effects of chain length on Rouse modes and non-Gaussianity in linear and ring polymer melts
Shota Goto, Kang Kim, Nobuyuki Matubayasi
The dynamics of ring polymer melts are studied via molecular dynamics simulations of the Kremer-Grest bead-spring model. Rouse mode analysis is performed in comparison with linear…
