What is geoscience?
Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth's surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more...

While the phenomenon, namely bulk-boundary correspondence, is inspired by topological insulators, the fundamental physics here is rather classical, not quantum. It appears quantamagazine has since updated the title (physics -> physicists), but not the url.
What's interesting here is they were able to verify the bulk topological characters (winding number around the zero of the wave function, ie the vortex) via observational data. In physics it's usually the other way around: the edge phenomenon, that is the edge spectral flow, is easier to measure than the elusive phase winding of the bulk wave function.
Incidentally, the original theory paper from Delplace et al came out right after the physics Nobel prize was awarded to topological physics.
