Title: A Hundred Years of Quantum Tunneling: from microscopic to macroscopic

Speaker: Prof. Peng Xiong

Time: 15:00, 14 October (Wednesday)

Location: Room 215, No. 8 Hainayuan Building

Abstract：

This talk reviews several key historical milestones in conceptual development and experimental demonstration of the phenomena of quantum mechanical tunneling, culminating in the experiments by Martinis, Devoret, and Clarke in the mid-1980s that, for the first time, clearly demonstrated quantum tunneling at macroscopic scale. The talk highlights the equal importance of being theoretically adventurous and experimentally rigorous in producing scientific breakthroughs.

Bio：

Peng Xiong received B.Sc. in Physics from University of Science and Technology of China in 1987 and Ph.D. in Physics from Brown University in 1993. He then spent the next four years as a postdoctoral fellow at the University of California at San Diego. He joined the Physics faculty of Florida State University in 1997. He is a recipient of the Alfred P. Sloan Research Fellowship, an APS fellow, and Distinguished Research Professor at Florida State University. His research activities have spanned superconductivity and quantum phase transitions in 2D and 1D systems, correlated electron physics, spin polarized transport in ferromagnet/normal metal, ferromagnet/superconductor, and ferromagnet/semiconductor heterostructures, and novel charge and spin transport in organic/solid-state hybrid nanostructures.
