Knotted Solitons

, 2016
The dynamical model on 3+1 dimensional spacetime admitting soliton solutions is discussed. The proposal soliton is localized in the vicinity of a closed contour, which could be linked and/or knotted. The topological charge is Hopf invariant. Some applications in realistic physical systems are indicated.

Topological Solitons

, 2004
Topological solitons occur in many nonlinear classical field theories. They are stable, particle-like objects, with finite mass and a smooth structure. Examples are monopoles and Skyrmions, Ginzburg-Landau vortices and sigma-model lumps, and Yang-Mills instantons.

Direct Observations of Large‐Scale Wave Structure and Post‐Sunset Rise of the Ionosphere in the Generation of Equatorial Spread F

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Large‐scale wave structure (LSWS) and the post‐sunset rise (PSSR) are two key factors in the generation of equatorial spread F (ESF). In this study, we reported continuous and direct observations of LSWS and PSSR and their effects on seeding ESF by Sanya incoherent scatter radar (SYISR) and ionosonde in September–October 2024.

Fission of quasi-static dissipative solitons in chiral nematics

Giant
Dissipative solitons in liquid crystals (LCs) are represented by three-dimensional solitary waves of director deformation called directrons. The only one exception on the quasi-static counterparts of directrons has ever been observed in achiral nematics.

The Short and Long Timescale Responses of the Inner Magnetospheric EMIC Waves to the Solar Wind Dynamic Pressure

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The causal relationships between solar wind dynamic pressure and Electromagnetic Ion‐Cyclotron (EMIC) H+ ${\mathrm{H}}^{+}$, He+ ${\mathrm{H}\mathrm{e}}^{+}$, O+ ${\mathrm{O}}^{+}$ waves at L=3−6 $L=3-6$ are investigated with transfer entropy at short (<15 ${< } 15$ min) and long (>45 ${ >} 45$ min) timescales. The short timescale responses of

The Two Modified G′G-Expansion Methods for Obtaining Solitons of the Korteweg-De Vries Equation

Advances in Mathematical Physics
The Korteweg-de Vries (KdV) equation plays an important role in describing the propagation of water waves in shallow channels. Several analytical methods, such as tanh-function methods (TFMs), exponential function method, and Jacobi elliptic function ...

Wavelength and interval tunable second-order bound solitons in mode-locked fiber laser based on Lyot filter

Results in Physics
The wavelength and interval tunable second-order bound solitons are generated in a nonlinear polarization rotation mode-locked fiber laser based on a Lyot filter in this paper. The Lyot filter structure is composed of two polarization controllers, two in-

Hermite–Gaussian solitons in 1+2 dimensional nonlocal nonlinear systems with Y0-oscillatory response

AIP Advances
We investigate the Hermite–Gaussian solitons in 1+2 dimensional nonlocal nonlinear systems with Y0-oscillatory response. The iterative solution of the solitons is numerically found using the accelerated imaginary-time evolution method with amplitude ...

Spontaneous symmetry breaking for solitons and local meta-stability: an elliptic functions based formulation

European Physical Journal C: Particles and Fields
We show that in an elliptic function based formulation for fields with large amplitudes, the rolling down of solitons towards the degenerate vacua can be described as transitions through local meta-stable potentials; the kink-like solitons constructed ...
