Self-Consistent Random Phase Approximation from Projective Truncation Approximation Formalism
Yue-Hong Wu, Xinguo Ren, Ning-Hua Tong
We derive the self-consistent random phase approximations (sc-RPA) from the projective truncation approximation (PTA) for the equation of motion of two-time Green's function. The o…
Direct minimization on the complex Stiefel manifold in Kohn-Sham density functional theory for finite and extended systems
Kai Luo, Tingguang Wang, Xinguo Ren
Direct minimization method on the complex Stiefel manifold in Kohn-Sham density functional theory is formulated to treat both finite and extended systems in a unified manner. This…
correlated calculations without finite basis-set error: Numerically precise all-electron RPA correlation energies for diatomic molecules
Hao Peng, Xinguo Ren
In wavefunction-based quantum mechanical calculations, achieving absolute convergence with respect to the one-electron basis set is a long-standing challenge.…
Full orbital calculation scheme for materials with strongly correlated electrons
V. I. Anisimov, D. E. Kondakov, A. V. Kozhevnikov +12
We propose a computational scheme for the ab initio calculation of Wannier functions (WFs) for correlated electronic materials. The full-orbital Hamiltonian H is projected into the…
