Probing Anharmonic and Heterogeneous Carrier Dynamics Across Sublattice Melting in a Minimal Model Superionic Conductor
Sucharita Niyogi, Takenobu Nakamura, Genki Kobayashi +2
Despite decades of research, the microscopic origin of sublattice melting and fast ion transport in superionic conductors remains elusive. Here, we introduce a chemically neutral m…
Persistent homology elucidates hierarchical structures responsible for mechanical properties in covalent amorphous solids
Emi Minamitani, Takenobu Nakamura, Ippei Obayashi +1
Understanding how atomic-level structures govern the mechanical properties of amorphous materials remains a fundamental challenge in solid-state physics. Under mechanical loading,…
Gibbs Factorials Become Kinetic in History-Dependent Reactions
Nanako Hirano, Akira Yoshida, Takenobu Nakamura +1
Gibbs factorials are usually regarded as equilibrium counting factors. We show that they can also appear directly in a measurable kinetic observable when products formed at differe…
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…
