“…Specifically, the coupling between CDW order and SC in AV 3 Sb 5 compounds has been experimentally explored through several approaches. These include tracking the evolution of both order parameters as the system is perturbed via chemical pressure (Ortiz et al, 2023;Liu et al, 2022a,b;Zhou et al, 2023), change in dimensionality (Song et al, 2021;Wang et al, 2021;Song et al, 2023), external pressure (Wang et al, 2021;Feng et al, 2023;Zhu et al, 2022;Wang et al, 2021;Du et al, 2022;Yu et al, 2022;Zheng et al, 2022), uniaxial strain (Qian et al, 2021), and chemical doping (Oey et al, 2022a;Oey et al, 2022b;Liu et al, 2023;Ding et al, 2022;Sur et al, 2023). One function of these perturbations is to shift the chemical potential about the multiple Van Hove singularities nearby; however, the dominant perturbation in the case of doping is often considered to be the orbitally selective modification of the Sb p z pocket at the Γ point in the Brillouin zone (LaBollita and Botana, 2021).…”
