Topic: Magnetic Topological Quantum Chemistry and High-Throughput Calculations of Magnetic Topological Materials

Host: Kai Chang,Professor,Beijing Academy of Quantum Information Sciences

Speaker:Yuanfeng Xu, Postdoc., Max Planck Institute of Microstructure Physics& Princeton University


Abstract: 

Topological quantum chemistry has enabled the understanding of and the high-throughput searching for symmetry indicated paramagnetic topological materials. In this talk,  I’ll briefly review the recent progress of magnetic topological materials, including magnetic Weyl semimetals and Axion insulators. Then, I’ll introduce the development of magnetic topological quantum chemistry (MTQC) [1] and the algorithm to determine the symmetry indicated topologies in the 1651 Shubnikov space groups [1, 2]. Finally, I’ll talk about some new topological phases in magnetic space groups [1] and several new magnetic topological materials found by high-throughput calculations [2].
