Abstract：

We　study　the　ultrafast　dynamics　of　the　multiband　iron-based　superconductor　CaKFe4As4　via　time-resolved　optical　reflectivity.　We　observe　a　long-lived　5-GHz　oscillation　of　the　reflection　changes　within　the　superconducting　regime.　We　assign　this　low-frequency　oscillation　to　a　soft　Leggett　mode　associated　with　the　collective　fluctuation　of　multiple　phase　differences　between　Cooper　pair　condensates.　Our　observation　evidences　the　presence　of　the　time-reversal-symmetry　breaking　state　in　superconducting　CaKFe4As4.
