Interface‐Induced Stability of Nontrivial Topological Spin Textures: Unveiling Room‐Temperature Hopfions and Skyrmions

Advanced Materials, Volume 38, Issue 1, 2 January 2026.
The first room‐temperature, zero‐field observation of stable skyrmion–hopfion spin textures in EuS─Bi2Se3─EuS trilayers is reported. Combining Lorentz TEM imaging and micromagnetic modeling, the authors unveil how interfacial Dzyaloshinskii–Moriya interaction and geometric confinement stabilize these multidimensional topological states.

Brittle and Crystal‐Plastic Defect Dynamics of Calcite Single Crystals

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract The response of Earth materials to stress has a first‐order control on solid‐Earth dynamics ranging from earthquakes to volcanic eruptions to landslides. Thus, understanding the rheological behavior of minerals, preferentially at a micro‐scale to allow process‐based upscaling, has broad applications across the Earth sciences.

On global behavior for complex soliton solutions of the perturbed nonlinear Schrödinger equation in nonlinear optical fibers

Journal of Ocean Engineering and Science, 2022
In this research article, the perturbed nonlinear Schrödinger equation (P-NLSE) is examined by utilizing two analytical methods, namely the extended modified auxiliary equation mapping and the generalized Riccati equation mapping methods.

Bright and Dark Breathers on an Elliptic Wave in the Defocusing mKdV Equation

Studies in Applied Mathematics, Volume 156, Issue 1, January 2026.
ABSTRACT Breathers on an elliptic wave background consist of nonlinear superpositions of a soliton and a periodic wave, both traveling with different wave speeds and interacting periodically in the space‐time. For the defocusing modified Korteweg–de Vries equation, the construction of general breathers has been an open problem since the elliptic wave ...

Dynamical Optical Structure Solutions of the Time‐Fractional Chen‐Lee‐Liu Equation

Advances in Mathematical Physics, Volume 2026, Issue 1, 2026.
In this article, we utilize the conformable fractional (CF) derivative to investigate the analytically innovative soliton solutions for the time‐fractional nonlinear perturbed Chen‐Lee‐Liu (CLL) equation in optical fibers. An essential governing equation in nonlinear optics, the perturbed CLL model describes the propagation of ultrashort pulses in ...

Effect of the nonlinear dispersive coefficient on time-dependent variable coefficient soliton solutions of the Kolmogorov-Petrovsky-Piskunov model arising in biological and chemical science

Heliyon
In this article, we study the soliton solutions with a time-dependent variable coefficient to the Kolmogorov-Petrovsky-Piskunov (KPP) model. At first, this model was used as the genetics model for the spread of an advantageous gene through a population ...
