Abstract
Tremendous interest has recently emerged in the kagome metal superconductors, since they are associated with an unconventional multicomponent charge density wave order parameter that may break time-reversal symmetry or obey other uncommon properties required for unconventional superconductivity. Here, the authors present spectroscopic evidence for the interplay between interacting order parameter components. The authors further develop a free-energy model and consistently describe experimental data, providing a basis for studying the interplay between multicomponent orders in the kagome metal systems.
