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…
Smectic-like bundle formation of planktonic bacteria upon nutrient starvation
Takuro Shimaya, Kazumasa A. Takeuchi
Bacteria aggregate through various intercellular interactions to build biofilms, but the effect of environmental changes thereupon remains largely unexplored. Here, by using an exp…
Vortex reversal is a precursor of confined bacterial turbulence
Daiki Nishiguchi, Sora Shiratani, Kazumasa A. Takeuchi +1
Active turbulence, or chaotic self-organized collective motion, is often observed in concentrated suspensions of motile bacteria and other systems of self-propelled interacting age…
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…
