Non-Abelian physics in light and sound. (https://pubmed.ncbi.nlm.nih.gov/38386745/)

These scientists wanted to understand how light and sound can behave in really interesting ways when they are manipulated in specific ways. They found that by changing certain aspects of light and sound, like their polarization or the materials they pass through, they can create different types of behaviors. This can help in creating devices that can do many things at once.

The scientists studied a lot of different areas of physics to explore these behaviors, such as atomic physics, condensed matter physics, and mathematical physics. They also looked at how light and sound can have special properties that can be used in technology.

In their study, they focused on things like geometric phases, topological charges, gauge fields, and braiding. They used these concepts to create new ways for light and sound to interact with each other. This research can help in developing new devices that can do more than what we have now.
