Prof. Junwei Liu is an associate professor in department of physics of The Hong Kong University of Science and Technology (HKUST). 

Prof. Liu has a broad interest in condensed matter physics and quantum physics, varying from the traditional phenomena like ferroelectricity to the exotic topological phases like quantum spin Hall insulators. His major contributions include (1) theoretical prediction of SnTe-type topological crystalline insulator, WTe2-type and TaIrTe4-type quantum spin Hall insulator; (2) discovery of the first monolayer ferroelectricity in SnTe thin films; (3) proposal of self-learning Monte Carlo methods that can be thousands of times faster than conventional methods without loss of any accuracy; (4) design and realization of the first all-optical deep neural networks; (5) proposal of crystal-symmetry-paired spin-valley locking in spin-splitting antiferromagnet (also called altermagnet); (6) realization of the first electrical readout and 180° switching of the Néel order in spin-splitting antiferromagnetic materials; and (7) discovery of the first two-dimensional altermagnet.
