Unconventional superconductors can host unusual electronic states, but understanding what drives their superconductivity becomes difficult when different forms of order coexist. The kagome metal CsV₃Sb₅ has become a particularly debated example.

It develops charge density wave order at about 94 K before becoming superconducting at about 2.5 K, yet experiments have offered conflicting views of whether its superconducting gap is conventional or contains nodes.

Resolving this question is important because knowing how superconductivity forms can guide the search for better superconducting materials.
