Interaction of coupled nonlinear oscillators having different intrinsic resting levels

Area of Science:

• Physics
• Nonlinear Dynamics
• Complex Systems

Background:

• Coupled oscillator interactions are typically governed by intrinsic frequency, amplitude, and coupling mechanisms.
• The role of other intrinsic properties, such as the resting level, in oscillator interactions remains less explored.

Purpose of the Study:

• To investigate the influence of the intrinsic resting level of coupled oscillators on their interaction dynamics.
• To determine if an intrinsic resting level gradient can govern oscillator interactions, independent of or in conjunction with frequency gradients.

Main Methods:

• Computer simulations were performed on chains of three and five bidirectionally coupled nonlinear oscillators.
• The study systematically varied intrinsic resting levels and intrinsic frequencies to observe emergent interaction patterns.

Main Results:

• An intrinsic resting level gradient was found to be a significant factor in governing coupled oscillator interactions.
• In the absence of an intrinsic frequency gradient, a resting level gradient alone was sufficient to produce many observed interaction features.
• When both intrinsic frequency and resting level gradients were present, their combined effects determined the interaction dynamics.

Conclusions:

• The intrinsic resting level is a crucial, previously underappreciated property governing coupled oscillator interactions.
• An intrinsic resting level gradient can act as a primary driver of complex interaction patterns in coupled oscillator systems.
• Future research should consider resting level dynamics when analyzing coupled oscillator systems in various scientific domains.
