Forced Oscillations01:06

Forced Oscillations

8.1K
When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of such oscillators are known as transients. After the transients die out, the oscillator reaches a steady state, where the motion is periodic, and the displacement is determined.

Oscillations In An LC Circuit

3.2K
An idealized LC circuit of zero resistance can oscillate without any source of emf by shifting the energy stored in the circuit between the electric and magnetic fields. In such an LC circuit, if the capacitor contains a charge q before the switch is closed, then all the energy of the circuit is initially stored in the electric field of the capacitor. This energy is given by

Oscillations about an Equilibrium Position

7.1K
Stability is an important concept in oscillation. If an equilibrium point is stable, a slight disturbance of an object that is initially at the stable equilibrium point will cause the object to oscillate around that point. For an unstable equilibrium point, if the object is disturbed slightly, it will not return to the equilibrium point. There are three conditions for equilibrium points—stable, unstable, and half-stable. A half-stable equilibrium point is also unstable, but is named so...

Damped Oscillations

7.4K
In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is termed undamped. However, friction of some sort usually dampens the motion, so it fades away or needs more force to continue. For example, a guitar string stops oscillating a few seconds after being plucked. Similarly, one must continually push a swing to keep a child swinging on a playground.
Although friction and other non-conservative...

RLC Circuit as a Damped Oscillator

2.4K
An RLC circuit combines a resistor, inductor, and capacitor, connected in a series or parallel combination.
Consider a series RLC circuit. Here, the presence of resistance in the circuit leads to energy loss due to joule heating in the resistance. Therefore, the total electromagnetic energy in the circuit is no longer constant and decreases with time. Since the magnitude of charge, current, and potential difference continuously decreases, their oscillations are said to be damped. This is...

Concept of Resonance and its Characteristics01:19

Concept of Resonance and its Characteristics

6.8K
If a driven oscillator needs to resonate at a specific frequency, then very light damping is required. An example of light damping includes playing piano strings and many other musical instruments. Conversely, to achieve small-amplitude oscillations as in a car's suspension system, heavy damping is required. Heavy damping reduces the amplitude, but the tradeoff is that the system responds at more frequencies. Speed bumps and gravel roads prove that even a car's suspension system is not...

Summary

Asymmetry-induced synchronization (AISync) is common in oscillator networks. Breaking system symmetry with nonidentical oscillators can stabilize complete synchronization, a phenomenon prevalent in multilayer networks.

Area of Science:

  • Physics
  • Network Science
  • Nonlinear Dynamics

Background:

  • Complete synchronization in oscillator networks typically relies on symmetry.
  • A recent study showed breaking symmetry can stabilize synchronization, termed asymmetry-induced synchronization (AISync).

Purpose of the Study:

  • To investigate the prevalence and general construction of AISync in oscillator networks.
  • To demonstrate that AISync is a common phenomenon across various physical systems.

Main Methods:

  • Developed a general scheme for constructing AISync systems.
  • Analyzed a wide class of physical systems modeled as multilayer networks.

Main Results:

  • Demonstrated that AISync is the norm, not the exception, in the studied systems.
  • Showed that AISync is prevalent in multilayer networks.

Conclusions:

  • AISync is a widespread phenomenon in oscillator networks, particularly in multilayer systems.
  • AISync likely plays a significant role in facilitating cluster synchronization by breaking subnetwork symmetry.
