On May 30, the first TDLI program: Topology in Physics started at the conference room of the 4th floor, Tsung-Dao Lee library. As the coordinator of the program, Prof. Jinfeng Jia hosted the first session of the program. At the opening, Senior Professor Xiangdong Ji from TDLI gave an introduction of TDLI and TDLI program. He emphasized the purpose of the program is to provide a platform for the participants to communicate and corporate with each other. Prof. Xiaoqun Wang, the dean of the School of Physics and Astronomy, also gave an introduction of the School.
The 2016 Nobel Prize in Physics was awarded to David J. Thouless, F. Duncan M. Haldane and J. Michael Kosterlitz "for theoretical discoveries of topological phase transitions and topological phases of matter". Topology plays very important role in in several areas such as condensed matter physics, quantum field theory and physical cosmology. Today as part of a "rise of topology", condensed matter physics is going through a mini-revolution. More recently, following the discovery of binary chalcogenides as topological insulators, the progress in the topological insulator research field has been remarkable.
For its importance, Tsung-Dao Lee Institute decided to assign the subject of the first TDLI program as Topology in Physics, which will be hold from May 29 to June 12, 2017. The program is designed to enhance interaction and collaboration among participants from worldwide in order to stimulate the vibrant, creative thinking that leads to insight and significant scientific progress.
Prof. Ji gave the first talk with title From Topology to Dark Matter. He introduced the application of topology in the theory of fundamental interaction and how the concept of Axion was proposed in consequence of topology.
