Biography(只提供英文版)

• Chair Professor and Dr William M W Mong Professor of Nanoscience in Department of Physics at The Hong Kong University of Science and Technology
• Research focus on the theoretical studies of possible topological states in correlated or non-equilibrium realistic material systems
• SRFS project — to examine three subjects related to strongly correlated and non-equilibrium topological states. 1) Addressing Landau Parameters in Topological Semi-Metals, Dr Dai aim to analyze chiral zero sound acoustic waves in these semi-metals using first-principle calculations. For materials with moderate correlation, Dr Dai'll employ a linear response theory rooted in density functional theory. For strongly correlated materials, the Gutzwiller variational method will compute susceptibility, leading to the Landau parameters. 2) Turning to 2D Moire Super-Lattice Systems, especially twisted bilayer graphene (TBG) and transition metal dichalcogenides (TMD), Dr Dai has modeled TBG's electronic properties, emphasizing its correlated and topological aspects. Leveraging pseudo zeroth Landau levels, the model will elucidate TBG's phase diagram, accounting for temperature, filling, and interaction strength. 3) Dr Dai'll probe Topological Many-Body Floquet States, focusing on 2D Moire superlattice systems like twisted multi-layer graphene or TMD under a robust periodic electric field.
