BOUND SOLITON STATES LOCALIZED NEAR DEFECT IN A NONLINEAR MEDIUM

Наука. Инновации. Технологии, 2022
Introduction: the relevance of the study is due to the fact that the effects of localization of excitations near the interfaces of nonlinear media play an important role in various technical applications of solid-state and opto-electronics.

A Thermodynamic Framework for Turing‐Type Instabilities in Porous Media: Part II Applications

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Compaction bands, desiccation cracks, and melt segregation structures are geological patterns relying on the same fundamental manifestations of a universal Turing‐type instability mechanism, as predicted by the thermodynamically consistent reaction–cross‐diffusion framework developed in Part I (Regenauer‐Lieb et al., 2025, https://doi.org/10 ...

Solliton-like order parameter distributions in the critical region

Condensed Matter Physics, 2006
Some exact one-component order parameter distributions for the Michelson thermodynamic potential are obtained. The phase transition of second kind in Ginzburg-Landau type model is investigated. The exact partial distribution of the order parameter in the

MMS Observation of Trapping of Electrons by Chorus Waves Inside a Magnetic Hole

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We present an event of chorus waves embedded within a magnetic hole (MH) in the Earth's magnetosheath, observed by the Magnetospheric Multi‐Scale (MMS) mission on 1 March 2016. Unlike conventional cases where chorus waves are typically detected near the center of a magnetic depression, in this event lower‐band chorus waves appear predominantly

Two‐Dimensional Equilibrium Model of Planetary Magnetotail in Generalized Nonthermal Plasmas

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Solar wind‐magnetosphere interaction may result in an elongated magnetotail with stored magnetic field energy. This study presents for the first time a family of asymptotic solutions for stretched two‐dimensional magnetotail equilibrium in generalized nonthermal plasmas, including the Kappa‐like and Maxwellian‐like velocity distributions with ...

Seismic Waves Do Sense Fracture Connectivity: Experimental Validation

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Fracture connectivity is a key parameter controlling fluid flow throughout the Earth's crust. While some theoretical and numerical studies suggest that seismic waves are sensitive to fracture connectivity, an experimental validation of this critically important phenomenon was so far unavailable.

Martian Atmospheric Loss Through Foreshock Transient Events

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract At Mars, the MAVEN spacecraft has made observations of Hot Flow Anomalies (HFAs) in the foreshock. Due to the bow shock's proximity to the planet, it is theorized that HFAs contribute to atmospheric escape at Mars through the excavation of ionospheric ions.

Detectability of Phytoplankton Biomass Extremes Using Simulated Satellite Chlorophyll Observations

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Extreme open‐ocean phytoplankton events can influence marine ecosystems, yet their global occurrence, drivers, and consequences remain poorly understood. Most large‐scale studies rely on satellite chlorophyll, which provides only a surface view, is affected by physiological variability, and is often missing due to clouds and low sunlight. Here,
