Then you should have a look into our new work, that was just published in Nature Communications, here. In this study, we observed what is called topological aberration for the first time in the lab, which means we were able to track the changes in complex twisted light fields in a way that has never been observed before…and might be useful in material characterizations. More info is also in the press release, here.
Congratulations to all co-authors, especially to Rafael who was leading the whole project!
