Rates of convergence of the partial-wave expansion beyond Kato's cusp condition II: evaluations for the prefactors on the ground state of the helium atom

Cong Wang

This article is a continuation of our previous work (Phys. Rev. A 88, 032511 (2013)). The prefactors for the partial-wave expansion of the helium atom are derived. Due to series of…

Twist-3 contributions to $γ γ \to π^{+} π^{-}, K^{+} K^{-}$ processes in perturbative QCD approach

Cong Wang, Jun-Kang He, Ming-Zhen Zhou

As one of the simplest hadronic processes, $γ γ \to M^{+} M^{-}$ ( $M = π, K$ ) could be a good testing ground for our understanding of the perturbative and nonperturbative structu…

A simple permutation group approach to spin-free higher-order coupled-cluster methods

Cong Wang, Gerald Knizia

We present a general-order spin-free formulation of the single-reference closed-shell coupled-cluster method. We show that the working equations of a fully biorthogonal contravaria…
