报告摘要:

Two-dimensional (2D) superconductors have become an important platform to study high Tc superconductivity and novel quantum physics. After a brief introduction to superconductivity and 2D superconductivity, I would like to talk about the recent progress in experimental studies for 2D crystalline superconductors. The topics are mainly focused on quantum metal state, quantum Griffiths singularity, Ising superconductivity, interface superconductivity, high Tc and topological superconductivity. [1-8]

报告人简介:

Jian Wang, Changjiang Distinguished Professor of China's Ministry of Education, received his bachelor’s degree in Physics from Shandong University in 2001, and PhD degree in condensed matter physics from Institute of Physics, Chinese Academy of Sciences in 2007. From 2006 to 2011, he worked as a Postdoc and Research Associate at Penn State University, USA. He became a tenure-track Associate Professor at Peking University in 2010 and promoted to Professor at Peking University in 2017. He was selected to Changjiang Distinguished Professor of China's Ministry of Education in 2016 and Chief Scientist for National Key R&D Program of China in 2018. He won Sir Martin Wood China Prize in 2015. His current research interests are quantum transport properties of low dimensional superconductors and topological materials. Jian Wang with collaborators discovered log-periodic quantum oscillations in a solid state system, quantum Griffiths singularity in 2D superconductors, tip-induced unconventional superconductivity in topological materials, interface-modulated Ising superconductivity, as well as for the first time demonstrated high Tc in one unit cell thick FeSe films by direct transport and Meissner evidences, revealed eletron-electron interaction in topological materials, and studied the heterostructures of topological/ferromagnetic materials and superconductors etc as one of the pioneers. In recent years, he has authored more than 80 papers including corresponding author publications in Science, Science Advances, Nature Materials, Nature Physics, Nature Communications, PNAS, Physical Review X, Physical Review Letters, Nano Letters, Advanced Materials etc. Jian Wang’s lab at Peking University possesses ultralow temperature-high magnetic field measurement systems and low temperature scanning tunneling microcopy/spectroscopy-molecular beam epitaxy combined ultrahigh vacuum system etc.
