Fluctuation--Response Relation in Finite-Size Noisy Coupled Phase Oscillators
Mrinal Sarkar, Yoshiyuki Y. Yamaguchi
Fluctuation--response relations (FRRs) provide a fundamental relation between spontaneous fluctuations and the linear response to external perturbations, yet their validity in non-…
Reconstruction of Phase Dynamics from Macroscopic Observations Based on Linear and Nonlinear Response Theories
Yoshiyuki Y. Yamaguchi, Yu Terada
We propose a novel method to reconstruct phase dynamics equations from responses in macroscopic variables to weak inputs. Developing linear and nonlinear response theories in coupl…
Discontinuous codimension-two bifurcation in a Vlasov equation
Yoshiyuki Y. Yamaguchi, Julien Barré
In a Vlasov equation, the destabilization of a homogeneous stationary state is typically described by a continuous bifurcation characterized by strong resonances between the unstab…
Mode selectivity of dynamically induced conformation in many-body chain-like bead-spring model
Yoshiyuki Y. Yamaguchi
We consider conformation of a chain consisting of beads connected by stiff springs, where the conformation is determined by the bending angles between the consecutive two springs.…
Dynamically induced conformation depending on excited normal modes of fast oscillation
Yoshiyuki Y. Yamaguchi, Tatsuo Yanagita, Tetsuro Konishi +1
We present dynamical effects on conformation in a simple bead-spring model consisting of three beads connected by two stiff springs. The conformation defined by the bending angle b…
Critical exponents in coupled phase-oscillator models on small-world networks
Ryosuke Yoneda, Kenji Harada, Yoshiyuki Y. Yamaguchi
A coupled phase-oscillator model consists of phase-oscillators, each of which has the natural frequency obeying a probability distribution and couples with other oscillators throug…
