 报告人简介

Zhaoliang  Liao graduated from University of Science and Technology of China with  a bachelor of Science Degree Major in Theoretic Physics in July 2006. He  received his first Ph. D degree in Physics in Institute of Physics of Chinese Academy of Science in  November 2011. He came to U.S. in January 2010 as a dual degree student and  started his graduate study in Department of Physics and Astronomy in  Louisiana State University (LSU) and  received his second Ph. D degree in LSU in December 2012. He was awarded 100  talent of Chinese Academy of Sciences in 2018 and is now a Professor in  University of  Science and Technology of China.

报告摘要

Oxide  heterostructures, which provide unprecedented opportunities to engineer delicate  coupling between spin, orbital, charge and lattice degrees of freedoms, are  attractive new  emergent quantum materials for diverse application. How to achieve desired  properties by design is at the forefront but very challenging topic. In this  talk, I will present the central concept of atomic synthesis and manipulation,  which bring us into a fundamental new stage where to discover and understand new  materials at atomic scale becomes possible. First I will discuss the concept of  atomic synthesis by introducing advanced epitaxial techniques. Then I will  present the idea of interfacial lattice control by playing with interfacial  symmetry mismatch, which can be used to effectively control the spin, charge and  orbital degree of freedom and lead to many novel phenomena.[1-3]By interfacial  and surface structure control, we are able to create two dimensional  ferromagnet, in which chiral spin fluctuation leads  to interesting topological Hall effect.[4]
