Intrinsic speed characteristics of a self-propelled camphor disk under repulsive perturbations
Yuki Koyano, Jerzy Górecki, Hiroyuki Kitahata
Camphor is a well-studied material capable of generating self-propelled motion at a water surface, and the resulting dynamics can exhibit a wide range of behaviors. Here, we analyz…
Energetics-based model for a diffusiophoretic motion of a deformable droplet
Hiroyuki Kitahata, Yuki Koyano, Yasuaki Kobayashi +1
We construct a mathematical model for a diffusiophoretic motion of a deformable droplet, which is floating on a liquid surface and is driven by the surface tension gradient origina…
Inferring Coupled Stuart-Landau Equations from Waveforms
Yuki Araya, Hiroaki Ito, Hiroshi Kori +1
We present a data-driven framework to infer phase-amplitude equations of coupled limit-cycle oscillators directly from waveform measurements. Exploiting the universality of the Stu…
Higher-codimension points as organizing centers in nonreciprocal pattern-forming systems with O(2)-symmetry
Yuta Tateyama, Daniel Greve, Hiroaki Ito +3
Focusing on a two-field Swift-Hohenberg model with linear nonreciprocal interactions, this study investigates how emerging higher-codimension points act as organizing centers for t…
Modeling the time evolution of a camphor rotor perturbed by a stationary camphor source
Jerzy Gorecki, Yuki Koyano, Hiroyuki Kitahata
A self-propelled motion resulting from the dissipation of camphor molecules on the water surface has been attracting scientific attention for more than 200 years. A generally accep…
Simple mathematical model for a pairing-induced motion of active and passive particles
Hiroaki Ishikawa, Yuki Koyano, Hiroaki Ito +2
We propose a simple mathematical model that describes a pairing-induced motion of active and passive particles in a two-dimensional system, which is motivated by our previous paper…
