Performance Optimization in Two-dimensional Brownian Rotary Ratchet Models
Hiroki Tutu, Katsuya Ouchi, Takehiko Horita
With a model for two-dimensional (2D) Brownian rotary ratchets being capable of producing a net torque under athermal random forces, its optimization for mean angular momentum (…
Performance Estimation for Two-Dimensional Brownian Rotary Ratchet Systems
Hiroki Tutu, Takehiko Horita, Katsuya Ouchi
Within the context of the Brownian ratchet model, a molecular rotary system was studied that can perform unidirectional rotations induced by linearly polarized ac fields, and produ…
Finite-size scaling in globally coupled phase oscillators with a general coupling scheme
Isao Nishikawa, Koji Iwayama, Gouhei Tanaka +2
We investigate a critical exponent related to synchronization transition in globally coupled nonidentical phase oscillators. The critical exponents of susceptibility, correlation t…
Long-term fluctuations in globally coupled phase oscillators with general coupling: Finite size effects
Isao Nishikawa, Gouhei Tanaka, Takehiko Horita +1
We investigate the diffusion coefficient of the time integral of the Kuramoto order parameter in globally coupled nonidentical phase oscillators. This coefficient represents the de…
Mapping Model of Chaotic Phase Synchronization
Hirokazu Fujisaka, Satoki Uchiyama, Takehiko Horita
A coupled map model for the chaotic phase synchronization and its desynchronization phenomenon is proposed. The model is constructed by integrating the coupled kicked oscillator sy…
Critical dynamics of phase transition driven by dichotomous Markov noise
Katsuya Ouchi, Takehiko Horita, Hirokazu Fujisaka
An Ising spin system under the critical temperature driven by a dichotomous Markov noise (magnetic field) with a finite correlation time is studied both numerically and theoretical…
