Light Control of Magnetism: A New Twist in Layered Materials
![The magnetoelectric Raman force response function [latex]\chi^{\alpha l}_{2}(\omega_{1},\omega_{2})[/latex]-where α denotes longitudinal or transverse components and [latex]l[/latex] represents the x or y direction-is determined by the interplay of four Green’s functions [latex]G_{1,..4}(\boldsymbol{k},i\omega_{n})[/latex] and symmetrized Bogoliubov transformations of 4x4 polarization matrices, establishing a framework for understanding complex material responses to external stimuli.](https://arxiv.org/html/2602.16785v1/x12.png)
Researchers have theoretically shown how electric fields can be used to manipulate magnetic states in a specific class of layered materials through a novel coupling between light and atomic vibrations.
