Spiraling solitons: A continuum model for dynamical phyllotaxis of physical systems
1Theoretical Division and Center for Nonlinear Studies, Los Alamos National Laboratory, Los Alamos, New Mexico 87545, USA.
Summary
A new model explains the protean topological soliton in repulsive particle systems. It describes features like locked speed, energy, and charge transport in various spiraling systems.
Area of Science:
- Condensed matter physics
- Theoretical physics
- Materials science
Background:
- Topological solitons are exotic quasiparticles with unique properties.
- Phyllotaxis, the arrangement of leaves on a plant stem, mathematically describes certain soliton structures.
- Previous models lacked a unified explanation for soliton dynamics in specific geometries.
Purpose of the Study:
- To develop a minimal, local continuum model for the protean topological soliton.
- To explain key dynamic features of the phyllotactic soliton, including speed, energy, and charge transport.
- To generalize the model for broader applications in spiraling systems.
Main Methods:
- Formulation of a continuum model based on number-theoretical phyllotaxis principles.
- Analysis of soliton dynamics, including locked speed and screw shift.
- Investigation of energy and charge transport mechanisms within the soliton framework.
Main Results:
- The model successfully explains locked speed, screw shift, and energy transport.
- It accounts for charge transport in Wigner crystals on nanotubes.
- The model predicts novel static and dynamic soliton pulses.
- It demonstrates the soliton's ability to exist between nondegenerate structures and extend its dynamics.
Conclusions:
- The developed continuum model provides a comprehensive explanation for the protean topological soliton.
- The findings have potential applications in charge transport and DNA transitions.
- The model's generality suggests applicability to diverse spiraling physical systems.

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...
01:21Partial Differential Equations
A stone dropped into a still pond generates waves that propagate outward in circular patterns, creating a dynamic surface whose elevation depends on both position and time. At any given location, the water level oscillates as the wave passes, while at any fixed moment, the surface exhibits smooth, curved structures extending across space. This dual dependence requires a mathematical description that accounts for variation in multiple variables simultaneously.At a fixed point on the water...
01:27Gauss's Law: Planar Symmetry
A planar symmetry of charge density is obtained when charges are uniformly spread over a large flat surface. In planar symmetry, all points in a plane parallel to the plane of charge are identical with respect to the charges. Suppose the plane of the charge distribution is the xy-plane, and the electric field at a space point P with coordinates (x, y, z) is to be determined. Since the charge density is the same at all (x, y) - coordinates in the z = 0 plane, by symmetry, the electric field at P...
01:25Divergence and Curl of Electric Field
The divergence of a vector is a measure of how much the vector spreads out (diverges) from a point. For example, an electric field vector diverges from the positive charge and converges at the negative charge. The divergence of an electric field is derived using Gauss's law and is equal to the charge density divided by the permittivity of space. Mathematically, it is expressed as
01:25Poisson's And Laplace's Equation
The electric potential of the system can be calculated by relating it to the electric charge densities that give rise to the electric potential. The differential form of Gauss's law expresses the electric field's divergence in terms of the electric charge density.
01:10First Law: Particles in One-dimensional Equilibrium
Newton's first law of motion states that a body at rest remains at rest, or if in motion, remains in motion at constant velocity, unless acted on by a net external force. It also states that there must be a cause for any change in velocity (a change in either magnitude or direction) to occur. This cause is a net external force. For example, consider what happens to an object sliding along a rough horizontal surface. The object quickly grinds to a halt, due to the net force of friction. If we...
