Self‐Similar Blowup for the Cubic Schrödinger Equation

Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1831-1918, August 2026.
ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.

Pure-high-even-order dispersion bound solitons complexes in ultra-fast fiber lasers

Light: Science & Applications
Temporal solitons have been the focus of much research due to their fascinating physical properties. These solitons can form bound states, which are fundamentally crucial modes in fiber laser and present striking analogies with their matter molecules ...

Strain Imaging of GaAs by Stimulated Raman Scattering Microscopy

Journal of Raman Spectroscopy, Volume 57, Issue 8, Page 1387-1391, August 2026.
Telecom‐wavelength stimulated Raman scattering (SRS) microscopy is developed for high‐throughput, nondestructive characterization of gallium arsenide (GaAs). By overcoming optical absorption limits of conventional Raman systems, this technique enables precise visualization of LO phonon frequency variations (< 0.2‐cm −1 precision).

Octave‐Spanning, Deterministic Single Soliton Generation in 4H‐Silicon Carbide‐On‐Insulator Microring Resonators

Laser &Photonics Reviews, Volume 20, Issue 15, 7 August 2026.
The miniaturization of metrology and precision spectroscopy systems requires robust, turn‐key microcombs with broad bandwidth, low threshold, and high efficiency. Here, high‐Q, dispersion‐engineered microresonators in a high‐confinement nonlinear SiC platform, combined with waveguide‐enabled thermal management and laser cooling, enable deterministic ...

A Wrong Ansatz for Nonlinear Waves in the Stochastic Maccari System

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 8, August 2026.
ABSTRACT This note is a short version of arXiv preprint arXiv:2508.12786 (2025), explicitly tailored to explain why the solutions of a stochastic Maccari system as found in ZAMM‐Journal of Applied Mathematics and Mechanics/Zeitschrift für Angewandte Mathematik und Mechanik 103, no. 5 (2023): e202100199. are wrong.

Temperature evolution of the high‐harmonic magnetic modulations in DyFeO3

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1332-1337, August 2026.
The temperature evolution of the high‐harmonic incommensurate magnetic ordering of Dy3+ in DyFeO3 orthoferrite is compared with the literature results on the soliton lattice of TbFeO3 observed in an external magnetic field.We report on the temperature evolution of magnetic satellites associated with the incommensurate magnetic ordering of Dy3+ ions in ...

Solitons in Interaction [PDF]

Progress of Theoretical Physics, 1987
Several new nonlinear systems are given which are completely integrable. These systems can be considered as flows describing the self-interaction of single solitons in multisoliton fields. The construction of action variables, recursion operators, bi-hamiltonian formulation and the like is performed for these nonlinear systems.

Estimating Surface Explosion Yield From Single‐Channel Infrasound Signals at Regional Distances With Random‐Forest Regression

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract When detonated on the Earth's surface, large explosions emit distinctive acoustic signatures that propagate over vast distances with relatively low attenuation in the form of infrasound. Infrasound stations hundreds of kilometers from the impulsive source can record the propagated pressure signal, atmospheric conditions permitting.
