Summary
Scientists created two-dimensional chimera states in coupled waveguide arrays. These states exhibit coexistence of coherent and incoherent light emission, displaying spatiotemporal chaos.
Area of Science:
- Optics and Photonics
- Nonlinear Dynamics
- Condensed Matter Physics
Background:
- Coupled waveguide arrays and microcavities are used to control light.
- These systems can exhibit complex behaviors under external influence.
Purpose of the Study:
- To investigate the generation and properties of two-dimensional chimera states in coupled optical systems.
- To explore the coexistence of coherent and incoherent light emission within these structures.
Main Methods:
- Utilizing a paradigmatic envelope equation model.
- Applying coherent optical injection to the waveguide arrays.
- Analyzing system dynamics through Lyapunov spectrum and Yorke-Kaplan dimension calculations.
Main Results:

1.3K
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

According to the theory of resonance, if two or more Lewis structures with the same arrangement of atoms can be written for a molecule, ion, or radical, the actual distribution of electrons is an average of that shown by the various Lewis structures.

3.1K
Resonance is produced depending on the boundary conditions imposed on a wave. Resonance can be produced in a string under tension with symmetrical boundary conditions (i.e., has a node at each end). A node is defined as a fixed point where the string does not move. The symmetrical boundary conditions result in some frequencies resonating and producing standing waves, while other frequencies interfere destructively. Sound waves can resonate in a hollow tube, and the frequencies of the sound...

The parallel RLC circuit is an arrangement where the resistor (R), inductor (L), and capacitor (C) are all connected to the same nodes and, as a result, share the same voltage across them. The parallel RLC circuit is analyzed in terms of admittance (Y), which reflects the ease with which current can flow. The admittance is given by:
