Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract The 29 July 2025 Mw 8.8 Kamchatka earthquake generated notable seismic and tsunami waves. The total electron content (TEC) derived by more than 1,400 ground‐based global navigation satellite system (GNSS) receiving stations in Japan and Taiwan is employed to examine the spatiotemporal evolution of seismic‐ and tsunami‐traveling ionospheric ...

Non-topological solitons and quasi-solitons
Reports on Progress in PhysicsAbstract Solitons in relativistic field theories are not necessarily topologically charged. In particular, non-topological solitons—known as Q-balls—arise naturally in nonlinear field theories endowed with attractive interactions and internal symmetries.

Unprecedented Extreme Dust Storm Triggered by Stratosphere‐Troposphere Interactions
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract An unprecedented dust storm struck southern China in April 2025, affecting hundreds of millions of people in regions rarely impacted by dust storms and challenging existing understanding of lower‐latitude dust storms. Here, we show that polar stratospheric signals enabled this event by modulating tropospheric teleconnection, revealing an ...

Vortex Light Bullets Guided by Disclination Defects
Nanophotonics, Volume 15, Issue 14, 27 July 2026.A new class of stable and thresholdless light bullets carrying vorticity, guided by the disclination defects introduced into Su–Schrieffer–Heeger‐like lattices with a focusing cubic nonlinearity, is reported. Different discrete rotational symmetry of the aperiodic lattice determines the allowed values of the topological charge of the vortex bullets ...

Rigidity Characterizations of Conformal Solitons
MathematicsWe study the rigidity of conformal solitons, give a sufficient and necessary condition that guarantees that every closed conformal soliton is gradient conformal soliton, and prove that complete conformal solitons with a nonpositive Ricci curvature must ...

Third Harmonic Generation in Transparent Longitudinal Epsilon‐Near‐Zero Multilayers
Nanophotonics, Volume 15, Issue 14, 27 July 2026.Transparent longitudinal epsilon‐near‐zero stacks enable field‐enhanced nonlinear light generation while preserving high near‐infrared pump transmission. Broadband third‐harmonic generation is experimentally observed demonstrating that TLENZ architectures can mitigate pump‐loss limitations and offer a promising platform for transparent nonlinear ...

Beam Steering in Nonlocal Mediumwith Competing Nonlinearities
Journal of Harbin University of Science and Technology, 2017 Nonlocal spatial solitons have potential applications in all-optical signal processing and optical interconnects due to their low power and particle-like nature on interactions.
