Yang Xu is currently interested in strong correlation and topological effects in low-dimensional quantum materials, which are typically probed by transport or optical methods in his lab at the Institute of Physics, Chinese Academy of Sciences (IOP CAS). He studied quantum transport on 3D topological insulators and earned his PhD from Purdue University in 2018. Following that, he completed a two-and-a-half-year postdoctoral fellowship at Cornell University, where he primarily focused on emergent physics in 2D moiré superlattices. In December 2020, Yang joined the Institute of Physics, Chinese Academy of Sciences, and became a Principal Investigator in Group N08 in 2023. His team is dedicated to developing cutting-edge methods for studying and manipulating these materials. Most of their research requires a broad range of experimental techniques, including micro- and nano-fabrication, electronic transport, and optical spectroscopy at ultralow temperatures and in high magnetic fields.
