New method identifies altermagnets by signatures from circularly polarized light, validated in MnTe, speeding discovery for ...

Altermagnets are a newly recognized class of antiferromagnets whose magnetic structure behaves very differently from what is found in conventional ...

A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...

Understanding optical resolution is key in microscopy, highlighting the diffraction limit and innovations in super-resolution ...

It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next ...

Optics meets 2D materials: a simple probe light beam exiting an optical moiré lattice can be chopped up into diffuse streaks or confined into a single bright spot, depending on the twist angle in the ...
