Soliton-mode proliferation induced by cross-phase modulation of harmonic waves by a dark-soliton crystal in optical media

, 2021
The generation of high-intensity optical fields from harmonic-wave photons, interacting via a cross-phase modulation with dark solitons both propagating in a Kerr nonlinear medium, is examined.

Exact Multisoliton Solutions of General Nonlinear Schrödinger Equation with Derivative

The Scientific World Journal, 2014
Multisoliton solutions are derived for a general nonlinear Schrödinger equation with derivative by using Hirota’s approach. The dynamics of one-soliton solution and two-soliton interactions are also illustrated.

Dampened Diurnal Cycles of Hot‐Wet Extremes in Urban Areas Contrast With Thermally Driven Daytime Stress in Rural Landscapes of Beijing‐Tianjin‐Hebei Region

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Hot‐wet extremes (HWEs) are intensifying in the Beijing–Tianjin–Hebei region, but their fine‐scale diurnal urban–rural contrasts remain unclear. Using summer observations from 1,962 automatic weather stations during 2016–2024, we identify threshold‐exceeding HWE days and show that urban areas experience more compound day–night and independent ...

Geomagnetic Field Influence on Trans‐Ionospheric HF Wave Propagation via Topside Z–to–O Mode Conversion

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Satellite observations during ionospheric modification experiments have reported trans‐ionospheric high‐frequency (HF) wave propagation even when the pump frequency lies below the peak plasma frequency. Such behavior is often attributed to large‐scale density irregularities that locally permit ordinary‐mode (O‐mode) propagation, but this does ...

Soliton-Propagation for Off-phase Pumping of Resoant frequency

, 2023
Soliton Fission of a second order soliton is slowed down by pumping the system with a single pulse, which is off-phase to the initial soliton. (Time-Domain and Frequency-Domain representation)

Dimensional Synthesis for Emulating Nonlinear Disclination Dynamics

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
(a) Intensity distributions of the 2D disclination lattice under corner‐site excitation in the linear (a1), weakly nonlinear (a2), and strongly nonlinear (a3) regimes. (b) Corresponding one‐dimensional synthesized lattices (1DSLs) obtained through Lanczos mapping under the same nonlinear regimes.

Soliton and breather splitting on star graphs from tricrystal Josephson junctions [PDF]

, 2019
We consider the interactions of traveling localized wave solutions with a vertex in a star graph domain that describes multiple Josephson junctions with a common/branch point (i.e., tricrystal junctions). The system is modeled by the sine-Gordon equation.

Two-dimensional stationary soliton gas

Physical Review Research
We study two-dimensional stationary soliton gas in the framework of the time-independent reduction of the Kadomtsev-Petviashvili (KPII) equation, which coincides with the integrable two-way “good” Boussinesq equation in the xy plane.

Coherent soliton propagation through doped optical fibers: cloning, breakup, and soliton interactions

Anais da Academia Brasileira de Ciências, 2001
The simultaneous propagation of two optical pulses through a doped nonlinear dispersive medium modelled by a resonant three-level system was investigated numerically, within the framework of a pair of coupled extended nonlinear Schrödinger equations ...
