Multi-ring necklace vortex solitons in Kerr nonlinear media with azimuthally modulated Bessel potentials
Summary
Stable, high-winding-number necklace solitons were discovered, unlike unstable conventional vortex beams. This breakthrough enables new methods for manipulating complex light fields using stable vortex necklaces.
Area of Science:
- Nonlinear optics
- Optical solitons
- Bose-Einstein condensates
Background:
- Conventional vortex beams with high topological charges are inherently unstable.
- Vorticity-carrying necklace solitons offer potential for stable light field manipulation.
Purpose of the Study:
- To investigate the existence, stability, and dynamics of single- and multi-ring necklace solitons.
- To explore the influence of Kerr nonlinearity and Bessel-lattice potentials on soliton behavior.
Main Methods:
- Theoretical analysis of necklace solitons in a Bessel-lattice potential.
- Numerical simulations to study stability and dynamics of various necklace configurations (monopoles to 12-poles).
Main Results:
- Demonstrated stable single- and multi-ring necklace vortex patterns, including high-winding-number structures.
- Observed stable breathing dynamics in octupole necklaces and potential stability in 12-pole necklaces.
- Contrasted stability with the inherent instability of conventional high-topological-charge vortex beams.
Conclusions:
- The Bessel-lattice potential and Kerr nonlinearity enable the formation of stable necklace solitons.
- These stable vortex necklaces, especially high-winding-number ones, offer a novel platform for complex spatiotemporal light field manipulation.

01:20Bessel Function of Order Zero
A common physical example of wave propagation with radial symmetry is the ripple formed when a stone is dropped into a still pond. The disturbance originates at a central point and travels outward as a circular wave. As the radius of the wavefront increases, the same initial energy is distributed along a progressively larger circumference. Consequently, the amplitude, or height, of the wave decreases with distance from the center. This decay behavior cannot be captured by simple sine or cosine...
01:28Standing Waves in a Cavity
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:
01:11Atomic Nuclei: Larmor Precession Frequency
The earth's gravitational field produces a 'twisting force' perpendicular to the angular momentum of a spinning mass (such as a spinning top) that causes the mass to 'wobble' around the gravitational field axis in a phenomenon called precession. Similarly, the magnetic moment (μ) of a spinning nucleus precesses due to an external magnetic field directed along the z-axis. The precession of the magnetic moment vector about the magnetic field is called Larmor precession, and the angular frequency...
01:18Magnetic Field of a Solenoid
A solenoid is a conducting wire coated with an insulating material, wound tightly in the form of a helical coil. The magnetic field due to a solenoid is the vector sum of the magnetic fields due to its individual turns. Therefore, for an ideal solenoid, the magnetic field within the solenoid is directly proportional to the number of turns per unit length and the current. Conversely, the magnetic field outside the solenoid is zero.

01:23Atomic Nuclei: Nuclear Relaxation Processes
In the absence of an external magnetic field, nuclear spin states are degenerate and randomly oriented. When a magnetic field is applied, the spins begin to precess and orient themselves along (lower energy) or against (higher energy) the direction of the field. At equilibrium, a slight excess population of spins exists in the lower energy state. Because the direction of the magnetic field is fixed as the z-axis, the precessing magnetic moments are randomly oriented around the z-axis. This...
01:28Symmetry in Maxwell's Equations
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...
