Chemical Potentials and the One-Electron Hamiltonian of the Second-Order Perturbation Theory from the Functional Derivative Approach
Jiachen Li, Weitao Yang
We develop a functional derivative approach to calculate the chemical potentials of the second-order perturbation theory (MP2). In the functional derivative approach, the correlati…
Accurate Excitation Energies of Point Defects from Fast Particle-Particle Random Approximation Calculations
Jiachen Li, Yu Jin, Jincheng Yu +2
We present an efficient particle-particle random phase approximation (ppRPA) approach that predicts accurate excitation energies of point defects, including the nitrogen-vacancy (N…
Renormalized Singles with Correlation in Green's Function Theory for Accurate Quasiparticle Energies
Jiachen Li, Weitao Yang
We apply the renormalized singles with correlation (RSc) Green's function in the approximation to calculate accurate quasiparticle (QP) energies and orbitals. The RSc Green's…
Combining Localized Orbital Scaling Correction and Bethe-Salpeter Equation for Accurate Excitation Energies
Jiachen Li, Ye Jin, Neil Qiang Su +1
We applied localized orbital scaling correction (LOSC) in Bethe-Salpeter equation (BSE) to predict accurate excitation energies for molecules. LOSC systematically eliminates the de…
