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-

Gravity Wave Influences on MSTID Climatology Over CONUS: WACCM‐X Year‐Long Simulation and GNSS Long‐Term Observation

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Medium‐Scale Traveling Ionospheric Disturbances (MSTIDs) are prominent wave‐like structures in the ionosphere, with complex generation mechanisms involving both atmospheric gravity waves (GWs) and electrodynamic instabilities such as the Perkins instability (PI).

Highly localized horseshoe ripplons and solitons in positive dispersion media [PDF]

In this study, we systematically review various ripplon solutions to the Kadomtsev–Petviashvili equation with positive dispersion (KP1 equation). We show that there are mappings that allow one to transform the horseshoe solitons and curved lump chains of

Hydrographic Variability and Sound‐Channel Dynamics in the Nordic Seas: Implications for Predicting Acoustic Arrival Structure

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract Warm, saline Atlantic waters and fresher Arctic‐origin waters converge in the central Nordic Seas, creating strong mesoscale and submesoscale variability that influences both hydrography and sound propagation. During the Northern Ocean Rapid Surface Evolution 2022 experiment, high‐resolution temperature and salinity measurements were collected

Drivers of F‐Region Ionosphere Tidal Variability Caused by the Madden Julian Oscillation: Separating E‐Region Dynamo and Field‐Aligned Wind Effects

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The Madden–Julian Oscillation (MJO), a recurring intraseasonal (30–96 days) disturbance in the troposphere, strongly influences the E‐region and F‐region ionosphere through its modulation of atmospheric tides. Among these, the diurnal eastward wave number 3 (DE3) tide, driven by MJO‐modulated latent heating, carries MJO signals upward into the

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 ...

The Proton‐Alpha Instability as a Source of Ion Heating at Earth's Bow Shock

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Electrostatic waves are frequently observed at collisionless shocks and are believed to play a key role in energy dissipation. Recent spacecraft observations have identified a proton‐alpha instability in the Earth's bow shock as a potential mechanism to dissipate the energy associated with a relative drift between protons and alpha particles ...

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 ...

Stability of KdV Solitons on the Half‐Line: A Study for Nonhomogeneous Boundary Conditions

Studies in Applied Mathematics, Volume 156, Issue 6, June 2026.
ABSTRACT We study the orbital stability and asymptotic stability problems for KdV solitons on the right half‐line for nonhomogeneous boundary conditions in the energy space H1(R+)$H^1(\mathbb {R}^+)$. This paper improves the results of Cavalcante and Muñoz [Revista Matemática Iberoamericana 35, no. 6 (2019); and SIAM Journal on Mathematical Analysis 55,

Discrete Solitons of the Ginzburg-Landau Equation

, 2022
In this chapter we review recent results concerning localized and extended dissipative solutions of the discrete complex Ginzburg-Landau equation. In particular, we discuss discrete diffraction effects arising both from linear and non-linear properties ...
