Persistence of charge density wave fluctuations in the absence of long-range order in a hole-doped kagome metal

Terawit Kongruengkit, Andrea N. Capa Salinas, Ganesh Pokharel +3

The kagome metals $A$V${}_3$Sb${}_5$ ($A$ = K, Rb, Cs) exhibit a complex interplay between charge density wave (CDW) order and superconductivity. In this study, we use ultrafast cohere…
