[超导实验室学术报告] Emergent Electronic Orders in Iron-Based Superconductors

Exotic electronic orders abound in the vicinity of high temperature superconductivity, providing a hotbed of quantum fluctuations that have been theoretically proposed to enhance superconductivity. In the first part of the talk, I will give an overview of the various symmetry-breaking electronic orders that have been discovered in the iron-based superconductors over the past decade, with a focus on the experimental evidence of the pervasive electronic nematic phase and its coupling to the orbital and spin degrees of freedom. In the second part of the talk, I will present very recent experimental evidence for a newly discovered charge order in the iron-pnictides ubiquitous on the hole-doped side close to the regime of optimal superconductivity. In doing so, it is revealed that high temperature superconductivity in iron-pnictides appears in a fantastically rich regime where all four fundamental degrees of freedom are actively entangled.
Dr. Ming Yi is a postdoctoral scholar at the University of California, Berkeley. She is interested in using various experimental tools such as angle-resolved photoemission spectroscopy and x-ray and neutron scattering to probe and understand the emergent electronic orders in quantum materials. Ming obtained her B.S. degree from the Massachusetts Institute of Technology and her PhD degree from Stanford University, both in Physics. She is a recipient of the Outstanding Dissertation Award of the International Organization of Chinese Physicists and Astronomers in 2016, the L’Oréal USA For Women In Science Fellowship in 2015, the NSF Graduate Research Fellowship in 2008, and the Malcolm Cotton Brown Award from MIT in 2007.
