Non-perturbative anharmonic first-principles calculations establish that the CDW in CsV3Sb5 is three-dimensional, triggered by L-point phonon instability from electron-phonon coupling, with anharmonic melting explaining the experimental transition temperature and absence of observed softening.

Ti hole-doping suppresses competing 2x2x2 and 2x2x4 charge density wave supercells in the first superconducting dome of CsV3-xTixSb5 while eliminating detectable charge correlations in the second dome, leaving superconductivity conventional and distinct from Sb-site Sn doping.

Phonon collapse and anharmonic melting of the 3D charge-density wave in kagome metals
Non-perturbative anharmonic first-principles calculations establish that the CDW in CsV3Sb5 is three-dimensional, triggered by L-point phonon instability from electron-phonon coupling, with anharmonic melting explaining the experimental transition temperature and absence of observed softening.
