  报告内容:
  A defining characteristic of complex transition-metal oxides (TMOs) is that they contain incompleted sub-shells thus having a multiple of possible ground states. This triggers their vast variety of physical properties, emerging froma complicated  competition between multiple energy scales and the close coupling with lattice and spin degrees of freedom. On one hand, both chemical and physical complexity presents a formidable challenge in condensed matter physics and materials science in general. On the other hand, the complexity is directly responsible for their tunability, offering a fabulous playground for making artificial structures of these materials with new quantum physics of matter.
  It has become increasingly clear that surfaces, interfaces, thin films and heterostructures of TMOs display a rich diversity of fascinating properties that are related, but not identical to, the bulk phenomena, while the origin is still fiercely contested. In this talk, I will introduce our ability in growing high quality thin films with atomically sharp interfaces, as well as powerful tools to characterize their properties down to atomic resolution. I will use several examples to illustrate that, such combination of growth and characterization techniques not only allow us to discover the unknown origin of conventional interface, but widely expand the opportunities to explore unconventional interfaces and search for novel quantum functionalities.

  Prof. Jiandi Zhang received B.S. and M.S. degrees in physics from the Nanjing University of Science and Technology in 1982 and the Chinese Academy of Science(CAS) in 1986, respectively. Then he was on the faculty of Shanghai Jiao Tong University between 1986 and 1989. He received his Ph.D. degree in physics from Syracuse University in 1994, spent about one year at University of Nebraska-Lincoln and 3 years as a postdoc fellow at Oak Ridge National laboratory/the University of Tennesseehttp://www.utk.edu/prior to joining the Florida International University as a faculty member in 1998. Starting from 2009, he became a full professor in physics at Louisiana State University. He is also a visiting professor at CAS since 2007. He has published more than 110 peer-reviewed research articles. He is a fellow of American Physical Society.
