Now, carefully arranged arrays of atoms have brought these possibilities a step closer, achieving negative refraction without the need for artificially manufactured metamaterials.

In such systems, light interacts with atoms in a controlled and precise manner, without the absorption losses that typically convert light into heat. These unique properties make atomic media a ...
