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…
Route to turbulence via oscillatory states in polar active fluid under confinement
Sora Shiratani, Kazumasa A. Takeuchi, Daiki Nishiguchi
We report a novel route to active turbulence, observed in numerical simulations of a polar active fluid model under confinement. To deal with large-scale computations with arbitrar…
Emergence of bacterial glass
Hisay Lama, Masahiro J. Yamamoto, Yujiro Furuta +2
Densely packed, motile bacteria can adopt collective states not seen in conventional, passive materials. These states remain in many ways mysterious, and their physical characteriz…
Phase-ordering kinetics in the Allen-Cahn (Model A) class: universal aspects elucidated by electrically-induced transition in liquid crystals
Renan A. L. Almeida, Kazumasa A. Takeuchi
The two-dimensional (2d) Ising model is the statistical physics textbook example for phase transitions and their kinetics. Quenched through the Curie point with Glauber rates, the…
