An -adaptive Tetrahedral Spectral Element Method with Applications to Kohn-Sham Density Functional Theory
Zeyu Wang, Hongfei Zhan, Guanghui Hu
High-order -adaptive spectral element methods on tetrahedral meshes provide an effective framework for resolving localized singularities and multiscale structures in complex thr…
Reducing Spatial and Temporal Dimensionality in the Multidimensional Caldeira-Leggett Model
Hongfei Zhan, Ernest W. Z. Pan, Zhenning Cai
Focusing on the real-time dynamics of the reduced density matrix of the multidimensional Caldeira-Leggett model, several techniques are adopted in this paper to reduce the spatial…
A gradient flow model for ground state calculations in Wigner formalism based on density functional theory
Guanghui Hu, Ruo Li, Hongfei Zhan
In this paper, a gradient flow model is proposed for conducting ground state calculations in Wigner formalism of many-body system in the framework of density functional theory. Mor…
The Wigner Function of Ground State and One-Dimensional Numerics
Hongfei Zhan, Zhenning Cai, Guanghui Hu
In this paper, the ground state Wigner function of a many-body system is explored theoretically and numerically. First, an eigenvalue problem for Wigner function is derived based o…
