Producing monolayers and few-layers in high yield with environment-stability is still a challenge in hafnium disulphide (HfS2), which is a layered two-dimensional material of group-IV transition metal dichalcogenides, to reveal its unlocked…

Theoretical material investigation based on density functional theory (DFT) has been a breakthrough in the last century. Nevertheless, the optical properties calculated by DFT generally show poor agreement with experimental results…

Two-particle Green's functions and the vertex functions play a critical role in theoretical frameworks for describing strongly correlated electron systems. However, numerical calculations at two-particle level often suffer from large…
