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…
