When two electrons approach each other, the Coulomb force causes them to repel. However, when a group of electrons gathers within a solid material, they can coexist harmoniously, forming long-range ordered states such as spin, orbital, and charge orders, or pairing up to create a superconducting state with zero resistance. External parameters like pressure or magnetic fields can modulate the interactions between electrons, inducing transformations between different electronic states. This presentation will use the development of superconductivity over the past century as an example to briefly introduce the rich physical phenomena exhibited by collective electron motion, as well as the broad application prospects of superconductivity.
Professor Yuan Huiqiu is a Distinguished Professor at the Institute of Physics, Zhejiang University, Executive Deputy Director of the Center for Correlated Matter, and Chief Scientist of the National Key Research and Development Program. He received his Ph.D. in Natural Sciences from Dresden University of Technology, Germany, in 2003, followed by postdoctoral research at the University of Illinois at Urbana-Champaign and Los Alamos National Laboratory in the United States. He returned to China in 2008 to join Zhejiang University.
Professor Yuan has been selected as a Distinguished Professor by the Ministry of Education, a Leading Talent in Scientific and Technological Innovation by the National Program for Support of Top-notch Young Professionals, and an Outstanding Middle-aged and Young Expert in Zhejiang Province. He was elected as a Fellow of the American Physical Society and received the Ye Qisun Physics Prize from the Chinese Physical Society. He also enjoys a special government allowance from the State Council.
Professor Yuan's primary research focuses on the study of exotic electronic states in correlated electron materials under extreme conditions such as low temperatures, high pressures, and strong magnetic fields. His work has led to a series of innovative research achievements in areas such as heavy fermions, unconventional superconductivity, quantum phase transitions, and strongly correlated topological states. He has published more than 180 academic papers in prestigious journals such as RMP, Nature (3 articles), Science, and Nat. Phys.; he has led more than ten projects, including those under the National Key Research and Development Program and key projects of the National Natural Science Foundation; and he has delivered over 100 plenary or invited talks at important international conferences. Additionally, he serves as an advisory member for international conferences on strongly correlated electron systems and as an editorial board member for seven domestic and international journals, including Scientia Sinica.
All faculty and students are welcome to attend!
