Spatially-Periodic Cluster Pattern of Coupled Forced Oscillators
Hidetsugu Sakaguchi
We propose a simple model for periodic clustering of particles under forced oscillation. Effective viscosity is assumed to increase owing to neighboring particles by analogy with t…
The continuous spectrum of bound states in expulsive potentials
H. Sakaguchi, B. A. Malomed, A. C. Aristotelous +1
On the contrary to the common intuition, which suggests that a steep expulsive potential makes quantum states widely delocalized, we demonstrate that one- and two-dimensional (1D a…
Nonequilibrium Gaussian Distribution for Coupled Linear Langevin Equations
Hidetsugu Sakaguchi
Explicit forms of nonequilibrium Gaussian distributions and heat flows are obtained for the Fokker-Planck equation corresponding to the coupled linear Langevin equations of two and…
Nonequilibrium dynamics of coupled oscillators under the shear-velocity boundary condition
Hidetsugu Sakaguchi
Deterministic and stochastic coupled oscillators with inertia are studied on the rectangular lattice under the shear-velocity boundary condition. Our coupled oscillator model exhib…
Synchronization and spindle oscillation in noisy integrate-and-fire-or-burst neurons with inhibitory coupling
H. Sakaguchi, S. Tobiishi
We propose another integrate-and-fire model as a single neuron model. We study a globally coupled noisy integrate-and-fire model with inhibitory interaction using the Fokker-Planck…
Noise-induced synchronization for phase turbulence
H. Sakaguchi
Phase turbulence is suppressed by applying common noise additively to the Kuramoto-Sivashinsky type equation, and the noise-induced phase synchronization is realized. The noise str…
