Evolution and Conceptual Insights into the Geometric Phase of Light: A Comprehensive Review
Advanced Photonics Research, Volume 7, Issue 6, June 2026.This review presents a unified account of the geometric phase of light, linking its fundamental principles to diverse manifestations in polarization, spatial, and vector modes. By connecting theoretical frameworks with key experimental realizations, it reveals a coherent physical picture that deepens understanding and stimulates new directions in ...

Current‐Driven Nonreciprocal Response of Nonequilibrium Skyrmions
Advanced Science, Volume 13, Issue 31, 4 June 2026.A skyrmion holds great promise for spintronic applications owing to its intrinsic topological stability and high mobility under ultra‐low current excitation. Here, by means of in situ electron microscopy, we demonstrate a skyrmion diode effect and the associated current‐driven nonreciprocal skyrmion dynamics in a designed FeGe‐based microdevice.

Magnetic structure in the two‐dimensional van der Waals ferromagnet Fe3GaTe2
Journal of Applied Crystallography, Volume 59, Issue 3, Page 809-815, June 2026.High‐quality single crystals of Fe3GaTe2 were grown using the chemical vapour transport method, allowing for a precise determination of their crystal and magnetic structures. A shortening of the Fei–Fei distance enhances the Fe–Fe exchange interaction, providing a microscopic origin for its higher Curie temperature compared with Fe3GeTe2.High‐quality ...

Structural and magnetic investigations of the Weyl semimetal family CeAlSi1–xGex
Acta Crystallographica Section B, Volume 82, Issue 3, Page 250-257, June 2026.A systematic investigation is reported of the structural and magnetic evolution in the CeAlSi1–xGex series, combining X‐ray and neutron diffraction with magnetization measurements on polycrystalline samples and single crystals. Chemical substitution leads to a continuous lattice expansion and a suppression of the ferromagnetic ordering temperature ...

Communications in Mathematical Physics, 1987 A Skyrmion is a classical static field configuration of minimal energy in a nonlinear scalar field theory, where the Skyrmion represents a baryon and the scalar field is given by the pion. Mathematically a Skyrmion can be regarded as a topological non-trivial map from one Riemannian manifold to another (3-dimensional, orientable, connected), and the ...
