Imaging broken symmetry in the electronic structure of Bi-doped cuprates by scanning tunneling microscopy

ORAL

Abstract

The relationship between the mysterious pseudogap phase in the cuprate superconductors and the myriad broken symmetries observed by various experimental techniques is a source of much controversy. We use low-temperature scanning tunneling microscopy and spectroscopy to image electronic nematic order in the cuprate superconductor Bi2-xPbxSr2CuO6+$\delta $. We determine the robustness of the nematic order parameter to experimental conditions.
