Vanishing electronic nematic order beyond the quantum critical point in overdoped cuprate superconductors
ORAL
Abstract
The cuprate high-temperature superconductors involve a complex interplay between different structural and electronic symmetry-breaking phases. In the last decade, rotational and translational symmetry-breaking phases -- electronic nematicity and density wave order -- have been established as generic and distinct features in the cuprate phase diagram using different probes. In this study, we employ resonant x-ray scattering in the cuprate high-temperature superconductor Nd-LSCO to probe the relationship between electronic nematicity of the Cu 3d orbitals and hole doping. In the vicinity of the putative pseudogap quantum critical point, we find evidence for a considerable decrease in the measure of electronic nematicity as the degree of orbital asymmetry is reduced. These results identify electronic nematicity as a possibility for the ordered phase responsible for the quantum critical point in overdoped cuprates.
