Query: Two types of charge order in the superconducting kagome material
  CsV$_3$Sb$_5$   The kagome metals of the family $A$V$_3$Sb$_5$, featuring a unique structural
motif, harbor an array of intriguing phenomena such as chiral charge order and
superconductivity. CsV$_3$Sb$_5$ is of particular interest because it displays
a double superconducting dome in the region of the temperature-pressure phase
diagram where charge order is still present. However, the microscopic origin of
such an unusual behavior remains an unsolved issue. Here, to address it, we
combine high-pressure, low-temperature muon spin relaxation with
first-principles calculations. We observe a pressure-induced threefold
enhancement of the superfluid density, which also displays a double peak
feature, similar to the superconducting critical temperature. This leads to
three distinct regions in the phase diagram, each of which features distinct
slopes of the linear relation between superfluid density and the critical
temperature. These results are attributed to a possible evolution of the charge
order pattern from the superimposed tri-hexagonal Star-of-David phase at low
pressures (within the first dome) to the staggered tri-hexagonal phase at
intermediate pressures (between the first and second domes). Our findings
suggest a change in the nature of the charge ordered state across the phase
diagram of CsV$_3$Sb$_5$, with varying degrees of competition with
superconductivity.
