Invariant Measures for Soliton Systems Generated by Mealy Automata
Takahiro Kanazawa, Yutaro Nakabayashi
We study invariant measures for soliton systems described by Mealy automata. Motivated by recently introduced soliton models associated with 2-letter, 3-state Mealy automata, we fo…
Beyond local detailed balance: Microscopic rates reshape nonequilibrium phase behavior
Takahiro Kanazawa, Kyogo Kawaguchi, Kyosuke Adachi
Local detailed balance (LDB) is a central guiding principle for modeling nonequilibrium stochastic dynamics, yet it only constrains the ratio of forward and backward transition rat…
Hydrodynamic origins of symmetric swimming strategies
Takahiro Kanazawa, Kenta Ishimoto, Kyogo Kawaguchi
Efficient locomotion is important for the evolution of complex life, yet the physical principles selecting specific swimming strokes often remain entangled with biological constrai…
Locomotion on a lubricating fluid with spatial viscosity variations
Takahiro Kanazawa, Kenta Ishimoto
We studied locomotion of a crawler on a thin Newtonian fluid film whose viscosity varied spatially. We first derived a general locomotion velocity formula with fluid viscosity vari…
Dynamical phase transitions in single particle Brownian motion without drift
Takahiro Kanazawa, Kyogo Kawaguchi, Kyosuke Adachi
Dynamical phase transitions (DPTs) arise from qualitative changes in the long-time behavior of stochastic trajectories, often observed in systems with kinetic constraints or driven…
Universality in the dynamical phase transitions of Brownian motion
Takahiro Kanazawa, Kyogo Kawaguchi, Kyosuke Adachi
We study the dynamical phase transitions (DPTs) appearing for a single Brownian particle without drift. We first explore how first-order DPTs in large deviations can be found even…
