主讲人简介: Professor Junwei Liu earned his Ph.D. from Tsinghua University in 2014 and conducted postdoctoral research at MIT from 2014 to 2017. He joined the Hong Kong University of Science and Technology (HKUST) as an Assistant Professor in 2017 and was promoted to Associate Professor in 2023. His current research focuses on novel quantum phenomena arising from crystal symmetry and his related contributions include (1) theoretical proposal of crystal-symmetry-paired spin-valley locking in collinear spin-splitting antiferromagnets (also named altermagnet) and its realization and experimental verification in V2(Se, Te)2O-family materials, which is also the first layered quasi-2D altermagnets; (2) the first electrical readout and 180° switching of the Néel order in a collinear spin-splitting antiferromagnet, and (3) the first demonstration of multiple Majorana zero modes in a single vortex and their hybridization.
He has published more than 80 papers, including 2 in Science, 3 in Nature, 2 in Nature Physics, 3 in Nature Materials, 7 in Nature Communications, 1 in Physical Review X, 4 in Physical Review Letters, and 1 in Optica.
