Optics Express
|April 6, 2021
Summary
We studied spatial solitons in nonlocal media, finding that two-color vector solitons offer control but can spontaneously break symmetry during propagation.
Area of Science:
- Nonlinear optics
- Optical physics
- Condensed matter physics
Background:
- Spatial solitons are self-trapped light beams in nonlinear media.
- Competing nonlinear responses can lead to complex soliton dynamics.
- Nonlocal media exhibit light-matter interactions dependent on the surrounding environment.
Purpose of the Study:
- Investigate the formation and propagation of multi-hump spatial solitons.
- Explore solitons generated by one or two mutually incoherent light beams.
- Analyze the behavior of two-color vector supermode solitons.
Main Methods:
- Numerical simulations of nonlinear wave propagation.
- Analysis of scalar and vector soliton solutions.
- Perturbation theory for symmetry breaking analysis.
Main Results:
- Successfully generated multi-hump spatial solitons in a nonlocal medium.
- Observed distinct behaviors for single-beam and two-beam excitation.
- Demonstrated that two-color vector supermode solitons are controllable.
- Identified spontaneous symmetry breaking in vector soliton propagation.
Conclusions:
- Multi-hump spatial solitons can be formed and controlled in nonlocal media.
- Two-color vector supermode solitons present unique propagation characteristics, including symmetry breaking.
- Findings offer insights into light manipulation in complex optical systems.

A close look at earthquakes provides evidence for the conditions appropriate for resonance, standing waves, and constructive and destructive interference. A building may vibrate for several seconds with a driving frequency matching the building's natural frequency of vibration; this produces a resonance that results in one building collapsing while the neighboring buildings do not. Often, buildings of a certain height are devastated, while other taller buildings remain intact. This...

Once the fields have been calculated using Maxwell's four equations, the Lorentz force equation gives the force that the fields exert on a charged particle moving with a certain velocity. The Lorentz force equation combines the force of the electric field and of the magnetic field on the moving charge. Maxwell's equations and the Lorentz force law together encompass all the laws of electricity and magnetism. The symmetry that Maxwell introduced into his mathematical framework may not be...

One might wonder how the captain of a large ship can navigate through the ocean with just a turn of the steering wheel. The answer lies in the concept of two parallel forces that are equal in magnitude and opposite sense, creating a couple moment.
A couple moment is a rotational force that tends to rotate the steering wheel. The wheel's rotation can either be in a clockwise or anticlockwise direction. The right-hand rule is a helpful method for determining the direction of a couple moment....

5.9K
When two waves of the same nature occur in the same region simultaneously, they result in interference. Interference of waves implies that the net effect of the waves is the sum of the individual waves' effects. However, it does not imply that the individual waves affect the propagation of other waves.
Interference occurs in mechanical waves, such as sound waves, waves on a string, and surface water waves. Mechanical waves correspond to the physical displacement of particles. Hence,...

James Clerk Maxwell (1831–1879) was one of the significant contributors to physics in the nineteenth century. He is probably best known for having combined existing knowledge of the laws of electricity and the laws of magnetism with his insights to form a complete overarching electromagnetic theory, represented by Maxwell's equations. The four basic laws of electricity and magnetism were discovered experimentally through the work of physicists such as Oersted, Coulomb, Gauss, and...

The starting point for expressing the modes of standing waves is understanding the boundary conditions that the waves must follow. The boundary conditions are derived from the physical understanding of how the standing waves are sustained, that is, how the vibrating particles of the medium behave at the boundaries imposed on them.
For a tube open at one end and closed at the other filled with air, the modes are such that there is always an antinode at the open end and a node at the closed end....
