Summary
This study explores synchronization in light-powered oscillators. Strong interactions lead to in-phase synchronization, while weak interactions result in anti-phase synchronization.
Area of Science:
- Physics
- Materials Science
- Nonlinear Dynamics
Background:
- Self-excited oscillators harvest energy from their environment, enabling autonomous and portable applications.
- Synchronization and group behaviors in coupled oscillators are prevalent in natural systems.
Purpose of the Study:
- To theoretically investigate the synchronization of two coupled, light-powered self-excited oscillators made from liquid crystal elastomer (LCE) bars.
- To elucidate the mechanisms governing self-excited oscillation and synchronization modes.
Main Methods:
- Numerical calculations were performed on a theoretical model of LCE bar oscillators.
- Time histories of system quantities were analyzed to understand oscillation and synchronization dynamics.
- The influence of interaction strength, initial conditions, contraction coefficient, light intensity, and damping coefficient was extensively studied.
Main Results:
- Two synchronization modes were identified: in-phase and anti-phase.
- Strong interactions promote in-phase synchronization, whereas weak interactions favor anti-phase synchronization.
- Oscillator amplitude is influenced by contraction coefficient, gravity, light intensity, and damping, but generally not by initial conditions.
Conclusions:
- The interaction strength is the primary determinant of synchronization mode (in-phase vs. anti-phase).
- The theoretical framework provides insights into self-excited coupled oscillator synchronization.
- This research can be extended to understand large-scale synchronization phenomena in complex systems.

2.3K
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

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.

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...

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.
