Huygens' Coupled Pendulum
Two pendulums attached to a common support will eventually swing in opposite directions in perfect synchronization due to slight interactions between their motions.
Kuramoto Model
A mathematical model used to describe synchronization. It consists of a set of coupled limit cycle oscillators with differing natural frequencies that tend to synchronize their phases while oscillating at a common frequency.
Frequency Locking
The process by which the frequency of one oscillator becomes adjusted to a precise ratio with the frequency of another due to coupling.
Amplitude Death
When coupled oscillators, under certain conditions, settle into a stable state and stop oscillating altogether.
Stochastic Resonance
A phenomenon where the presence of noise enhances the response of a dynamical system to a periodic input signal, often resulting in improved signal detection or transmission.
Quasiperiodic Oscillations
Oscillations that result from the incommensurable frequencies of interacting dynamical subsystems leading to a trajectory that fills a torus in the phase space, without any periodic repetition.
Limit Cycle
A closed trajectory in phase space toward which the system's trajectories converge from various initial conditions, representing a stable oscillatory motion of the system.
Chimera States
A dynamical phenomenon where a network of identical oscillators splits into coexisting regions of synchronous and incoherent oscillations.
Noise-Induced Synchronization
A counterintuitive phenomenon where the introduction of noise into a system of coupled oscillators leads to a higher degree of synchronization amongst them.
Oscillatory Network Dynamics
The study of interconnected nodes or units that exhibit oscillatory behavior and are capable of complex patterns of synchronization and wave propagation.
Arnold Tongue
Regions in parameter spaces where synchronization can occur for a given frequency ratio between two coupled oscillators.
Circle Map
A simple model of a driven oscillator where the dynamics can exhibit very rich behavior including quasiperiodicity, mode-locking, and chaotic dynamics.
Bifurcation to Chaos
A sequence of bifurcations that a coupled dynamical system undergoes which leads to a chaotic state, with sensitive dependence on initial conditions and aperiodic long-term behavior.
Phase Locking
A phenomenon where two or more oscillators' phases become locked in a constant relationship due to interaction, so they oscillate at the same frequency.
Oscillator Chain
A sequence of interconnected oscillators where the dynamics of each one is influenced by its neighbors, leading to wave-like behavior or synchronization patterns.
