Wray， L. Andrew - 上海纽约大学 - 物理联合研究中心

个人简介

L. Andrew Wray is Assistant Professor of Physics. He holds a Ph.D. in Experimental Condensed Matter Physics from Princeton University (2010) and a B.A. in Physics from the University of California, Berkeley, and conducted pre-doctoral research at the Institute of Physics, Chinese Academy of Sciences. After completing his Ph.D., Wray led research projects at the Lawrence Berkeley National Laboratory (LBNL) and Stanford Institute for Materials and Energy Sciences (SIMES) prior to joining the NYU faculty in 2014. Wray’s research focuses on the discovery, characterization and manipulation of novel quantum states inside materials. His experiments have been instrumental in identifying the first realizations of topologically ordered quantum states of matter such as the topological insulator and topological superconductor. Incisive in-situ investigation of the energy and momentum profiles of quantum states is made possible by rapidly advancing capabilities at state of the art X-ray facilities. Wray maintains active involvement in proposing new X-ray science technologies and developing novel methods to simulate and analyze resonant interactions between X-rays and matter.
