About us

Welcome to Qihang Liu’s research group in the Department of Physics at SUSTech. Our research interest is theoretical condensed matter physics and computational materials science, special focus is on the new theories and effects of symmetry in quantum materials within the fields of spintronics and topological physics. Our recent achievements include:

(1) developing a symmetry description of magnetic-ordered systems, i.e., “spin group theory“, including the enumeration of spin point/space groups and the representation theory of spin space groups;

(2) developing an online program FINDSPINGROUP for identifying spin symmetries and related physical properties (i.e., spin splitting, anomalous Hall, quantum geometry, etc) for any given magnetic material;

(3) applying symmetry theory to predict exotic effects regarding unconventional magnetism, including antiferromagnetic spin splitting; antiferromagnetic hidden spin polarization, and correlation-enhanced spin-orbit coupling, etc;

(4) predicting the intrinsic magnetic topological family of Mn-Bi-Te with a superlattice structure, and proposing observable experimental phenomena for topological magnetoelectric effects.
