Symmetry-Informed Term Filtering for Continuum Equation Discovery
Junya Yokokura, Kazumasa A. Takeuchi
Discovering governing equations, whether manually or by data-driven methods, has been central in physics and related areas. Since governing equations are typically constrained by a…
Population dynamics simulations of large deviations for three subclasses of the Kardar-Parisi-Zhang universality class
Yuta Yanagibashi, Kazumasa A. Takeuchi
Recent theoretical studies have gradually deepened our understanding of the one-dimensional (1D) Kardar-Parisi-Zhang (KPZ) universality class even in the large deviation regime, bu…
Partial yet definite emergence of the Kardar-Parisi-Zhang class in isotropic spin chains
Kazumasa A. Takeuchi, Kazuaki Takasan, Ofer Busani +3
Integrable spin chains with a continuous non-Abelian symmetry, such as the one-dimensional isotropic Heisenberg model, show superdiffusive transport with little theoretical underst…
Rigidity transition of a highly compressible granular medium
Samuel Poincloux, Kazumasa A. Takeuchi
A wide range of disordered materials, from biological to geological assemblies, feature discrete elements undergoing large shape changes. How significant geometrical variations at…
