Berry phases in Coulomb drag of double-layer graphene system
Jianghui Pan, Lijun Zhu, Xiaoqiang Liu +3
Recent experiments suggest quantum interference effects in the Coulomb drag of double-layer graphene systems. By accounting for correlated interlayer impurity scattering under a we…
NeuralSCF: Neural network self-consistent fields for density functional theory
Feitong Song, Ji Feng
Kohn-Sham density functional theory (KS-DFT) has found widespread application in accurate electronic structure calculations. However, it can be computationally demanding especially…
Layered Kagome Compound NaNiS with Topological Flat Band
Junyao Ye, Yihao Lin, Haozhe Wang +4
We report structural and electronic properties of NaNiS, a quasi-two-dimensional compound composed of alternating layers of [NiS] and Na. The compo…
Assessing the atomic moment picture of spin dynamics: the perspective of \textit{ab initio} magnon wavefunction
Yihao Lin, Ji Feng
Our understanding of collective spin fluctuation in materials relies largely on Heisenberg-type spin Hamiltonians. Implicit in these spin models is the atomic moment picture that i…
