Superspace approach in elucidating the CDW modulation in Cs(V1-xTix)3Sb5 under pressure

A distinct interplay between charge density wave (CDW) and superconductivity is observed in the kagome metals AV3Sb5, where electronic instabilities can coexist, compete, or intertwine, creating rich opportunities for novel quantum phenomena. This proposal will investigate the atomic displacements amplitudes associated with the different CDW states observed in the kagome superconductor Cs(V1-xTix)3Sb5 under hydrostatic pressure. By targeted pressure tuning and applying superspace analysis we aim to resolve the atomic displacements involved in the CDW states. Our investigation will help clarify the transitions between commensurate-incommensurate modulations, identify the specific atomic sites primarily affected, and demonstrate how hydrostatic pressure and hole-doping at the kagome network influence the interplay between the CDW and superconducting states. These findings will enhance our understanding of symmetry breaking and phase competition in these systems.
