报告题目: X-ray Studies of Quantum Materials: from Unconventional Superconductivity to Topological Excitations

报告摘要: Correlated quantum materials possess remarkable physical properties, such as high-Tc superconductivity, anomalous Hall effect, novel topological orders etc. Yet, the underlining physics of these emergent quantum phenomena remain poorly understood. In recent few years, benefited by the fast development of new generation of x-ray light sources, ultra-high resolution inelastic x-ray scattering, fully coherent x-ray beam with nanometer x-ray spot, femtosecond time-resolution x-ray free electron laser (xFEL) become available to directly study the emerging low-energy excitations and their ultrafast processes. In this talk, I will present our works on various quantum materials and show how spin, charge and lattice excitations interact with each other and how these excitations conspire to determine the macroscopic physical properties. 

报告人简介：Hu Miao is a stuff Scientist at Oak Ridge National Laboratory. He received his PhD in condensed matter physics from the Institute of Physics, Chinese Academy of Sciences (IOP) in 2015. He then moved to Brookhaven National Laboratory as a postdoctoral research associate. His primary research interests are based on understanding emergent quantum phenomenon of strongly correlated and topological materials using advanced x-ray techniques. He is the author of 45 peer-reviewed scientific papers (including 9 Physical Review Letters, 5 Physical Review X, 3 Nature communications and 1 PNAS), which have received more than 3,000 citations (from Google Scholar).
