Evolution of charge correlations in the hole-doped kagome superconductor CsV3−𝑥Ti𝑥Sb5
The interplay between superconductivity and charge correlations in the kagome metal CsV3Sb5 can be tuned by external perturbations such as doping or pressure. Here we present a study of charge correlations and superconductivity upon hole doping via Ti substitution on the V kagome sites in CsV3−𝑥Ti𝑥Sb5 via synchrotron x-ray diffraction and scanning superconducting quantum interference device measurements. While the superconducting phase, as viewed via the vortex structure, remains conventional and unchanged across the phase diagram, the nature of charge correlations evolves as a function of hole doping from the first superconducting dome into the second superconducting dome.
