New methodology flips the script on topological physics

The department of arithmetic often called topology has change into a cornerstone of contemporary physics because of the outstanding — and above all dependable — properties it will possibly impart to a cloth or system. Sadly, figuring out topological methods, and even designing new ones, is mostly a tedious course of that requires precisely matching the bodily system to a mathematical mannequin. Researchers have demonstrated a model-free methodology for figuring out topology, enabling the invention of latest topological supplies utilizing a purely experimental method.
