What is the Kuramoto model used for?

The Kuramoto model (or Kuramoto–Daido model), first proposed by Yoshiki Kuramoto (蔵本 由紀, Kuramoto Yoshiki), is a mathematical model used to describe synchronization. More specifically, it is a model for the behavior of a large set of coupled oscillators.

What coupled oscillator?

Coupled Oscillations occur when two or more oscillating systems are connected in such a manner as to allow motion energy to be exchanged between them. Coupled oscillators occur in nature (e.g., the moon and earth orbiting each other) or can be found in man-made devices (such as with the pacemaker).

What is a pulse coupled oscillator?

Pulse coupled oscillators are limit cycle oscillators that are coupled in a pulsatile rather than smooth manner.

What are weakly coupled oscillators?

The theory of weakly coupled oscillators can be used to predict phase-locking in neuronal networks with any form of coupling. The theory of weak coupling allows one to reduce the dynamics of each neuron, which could be of very high dimension, to a single differential equation describing the phase of the neuron.

What is coupled pendula?

Two pendulums that can exchange energy are called coupled pendulums. The gravitational force acting on the pendulums creates rotational stiffness that drives each pendulum to return to its rest position.

What are normal modes in coupled oscillators?

A normal mode of an oscillating system is a pattern of motion in which all parts of the system move sinusoidally with the same frequency and with a fixed phase relation.

What does weakly coupled mean?

Forces which have a coupling constant greater than 1 are said to be “strongly coupled” while those with constants less than 1 are said to be “weakly coupled.”

What is the function of oscillators?

Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal. They are widely used in many electronic devices ranging from simplest clock generators to digital instruments (like calculators) and complex computers and peripherals etc.

What is the critical coupling strength for second order Kuramoto oscillators?

The Critical Coupling Strength for Second-Order Kuramoto Os- cillators. For m= n, D i= 1, and M i= M >0 the multi-rate Kuramoto model (1.3) simplifies to a second-order system of coupled oscillators with uniform inertia and unit damping.

What is Kuramoto’s model of synchronization?

The celebrated Kuramoto model captures various synchronization phenomena in biological and man-made dynamical systems of coupled oscillators. It is well-known that there exists a critical coupling strength among the oscillators at which a phase transition from incoherency to synchronization occurs.

What is the natural frequency of Kuramoto oscillators?

Simulation of a network of n = 10 Kuramoto oscillators satisfying K/K critical= 1.1, where the natural frequencies ω i: R ≥0→ [ω min,ωmax] = [0,1] are smooth, bounded, and distinct sinusoidal functions. Ultimately, each natural frequency ω i(t) converges to ω

What is a multi-rate Kuramoto model?

For m= n, D i= 1, and M i= M >0 the multi-rate Kuramoto model (1.3) simplifies to a second-order system of coupled oscillators with uniform inertia and unit damping. Such homogeneous second-order Kuramoto models have received some attention in the recent literature [14, 50, 49, 30, 29, 1, 2].
