However, despite firm observations, the atomistic origins of the CDW phases, as well as hidden instabilities, remain elusive. Here, we adopt our newly developed symmetry-adapted cluster expansion method to construct a first-principles-based effective Hamiltonian of CsV3Sb5, which not only reproduces the established inverse star of David (ISD) phase, but also predict a series of D3h-n states under mild tensile strains.
