Abstract
The nature of the superconductivity in the kagome metals AV3Sb5 (A = K, Rb, Cs) remains under debate. Here, using muon spin spectroscopy, the authors find that the superconductivity in RbV3Sb5 and KV3Sb5 evolves from nodal to nodeless with increasing pressure and the superconducting state breaks time-reversal symmetry after suppression of the charge order.
