Concentrating light in a volume as small as the wavelength itself is a challenge that is crucial for numerous applications.

In condensed matter physics as well as in photonics, systems which exhibit topological behaviour are widely studied. Using the theory of topology on materials, topological photonics look at the ...

As reported in Advanced Photonics, the researchers used multiple ... a specific spin texture known as a meron pair. A meron is a topological structure where the direction of the spin texture ...
