Abstract

In the cuprate superconductors, superconductivity often co-exists with other types of order, including charge density wave and nematic orders. Over the past decade, resonant x-ray scattering has emerged as a key tool to investigate these competing/coexisting orders, providing valuable insights into their microscopic character. In this report we provide a brief review of the technique and highlight selected recent advances in study charge density wave order and nematic order in the cuprates.
